摘要： A technique for operating a diode pumped solid state laser in a continuous-wave (cw) mode using diodes blocks (12) that are individually operated in a pulsed mode. For some high power laser applications, it is desirable to provide for operation in pulsed and cw modes, but pump diodes are typically designed for efficient operation in only one of these modes. The invention includes a controller (20) that pulses the individual diode blocks (12) on and off, but not necessarily in unison. For a pulsed mode of operation, the diodes (12) in an array are pulsed either at the same time, or sub-arrays are pulsed in a temporally interleaved manner for a higher effective pulse repetition rate. For the cw mode of operation, the diodes (12) are pulsed sequentially in sub-arrays (A-E), such that at least one sub-array is always energized and the complete array appears to be providing continuous pumping energy. In one embodiment, the sub-arrays (A-E) are columns of the array. In another embodiment, the sub-arrays (12') are each associated with a different solid-state gain medium (10'), the gain media being optically coupled in a single laser.
摘要翻译：使用以脉冲模式单独操作的二极管块（12）以连续波（cw）模式操作二极管泵浦固态激光器的技术。对于一些大功率激光器应用，期望提供在脉冲和cw模式中的操作，但是泵二极管通常被设计用于仅在这些模式之一中的有效操作。本发明包括控制器（20），该控制器（20）打开和关闭各个二极管块（12），但不一定是一致的。对于脉冲操作模式，阵列中的二极管（12）同时被脉冲，或者子阵列以时间交替的方式脉冲以获得更高的有效脉冲重复率。对于cw操作模式，二极管（12）在子阵列（A-E）中顺序地脉冲，使得至少一个子阵列总是被激励，并且整个阵列似乎提供连续的泵浦能量。在一个实施例中，子阵列（A-E）是阵列的列。在另一个实施例中，子阵列（12'）各自与不同的固态增益介质（10'）相关联，增益介质在单个激光器中光耦合。

摘要： The laser beam produced by the improved precision laser maintains an axial stability of less than 20 micro-radians in the presence of ambient temperature changes and shock and vibration of as much as 100 g's, achieving a new milestone in stability. In the new laser one end of the resonator (7) is hard mounted to the laser bench (13) and the other end of the resonator is mounted to that laser bench by a flexure (17). The flexure is designed to resiliently yield in the presence of thermally induced strain on the bench while retaining sufficient stiffness against foreseeable shock and vibration.

摘要： A beam monitoring assembly (10) that provides near-field imaging, far-field imaging and power measurements of a laser beam (12) in real-time for alignment and performance verification purposes. The monitoring assembly (10) includes a holographic beam splitter (24) that splits the laser beam (12) from the laser resonator cavity into a series of separate split beams (28, 30, 32) having varying beam powers. One of the split beams (28) is directed to a power meter (36) to measure the power of the beam (12). One of the split beams (28) is directed to a near-field camera (42) that provides a near-field image of the beam (12). Another one of the split beams (30) is directed to a heat dump (52) that absorbs and removes the beam's energy from the assembly. Another one of the split beams (32) is directed to a far-field lens (46) that focuses the split beam (32) onto a far-field camera (50) that provides a far-field image of the beam (12). The near-field and far-field images of the beam (12) are displayed on an operator control panel in real time. Suitable computer electronics (38) and camera electronics (58) are provided to process the electrical signals from the power meter (36) and the cameras (42, 50).

摘要： An optic cell 20 for use in the cavity of a high-power laser comprises an optic housing 22 which defines a first laser beam aperture 26. An optic element 32 such as a mirror or lens is disposed within the optic housing. A first indium layer 30 is between and in abutting contact with the optic housing and the optic element. An optic cover 40 defines a second laser beam aperture 46 therethrough substantially in alignment with the first laser beam aperture to form a window 47 of the optic element through which a laser beam passes. A second indium layer 48 is between and in abutting contact with the optic element and the optic cover. The optic housing and the optic cover are typically formed of aluminum or copper to passively cool the optic element. The first and second laser beam apertures are configured to minimize the heat transfer distance between the optic element and the optic housing and optic cover, and to allow the laser beam to pass through the optic element without striking metal portions of the optic cell. An optic cell mount 61 removably clamps the optic cell in the laser cavity, and includes cooling elements 56, 76 for cooling the optic cell to control the optic element temperature.

摘要： An optical bench 10 is cast from a single piece of material and provided with a number of optical component supports 14 which extend upwardly from a base 12. The optical component supports 14 are integral with the base 12, increasing their rigidity. The bench 10 may be cast with additional material in strategic areas to allow for future optimization of the bench 10—for example, the mounting of specific optical components throughout the bench 10. Further, the bench 10 may be provided with regions 24, 26, and 28 of varying rigidity by placing support struts 68 closer together in areas where greater rigidity is required. Apertures 30 may be provided in the bench 10 to enable the routing of conduits through the bench 10.

摘要： There is provided an optically pumped laser apparatus 10 which includes a heat conductive assembly 14 which is affixed to a solidstate yag laser crystal medium for generating a laser beam 49 within the laser crystal medium 12. The heat conductive assembly 14 comprises a heat diffusing element 32 which serves to diffuse the heat that is generated through the cooling surfaces 24 and 26. It includes a heat discharging structure 33 for removing the heat from the system. The efficiency of the laser system is improved by the geometry of pumping the crystal laser medium along the paths shown by the arrow 40 and to directing heat removed by the heat conductive assembly along the arrows 42, which paths are normal to one another and which provide an effective geometry that minimizes temperature variations within the laser crystal 12 to provide a low value for the OPD of the system. The heat conductive assembly 14 may include a liquid type heat exchanger 43, or heat pipes 33 to facilitate removal of the heat from the diffuser 32.

摘要： A compact fiber packaging system for fiber lasers is provided that comprises a series of spools nested inside one another for efficient volume utilization. The spools comprise an inner spool nested inside at least one outer spool to form a module. Generally, the fiber lasers are wrapped around the inner spool, and then around successive outer spools as required to form the module. Furthermore, the modules may be stacked to form a fiber assembly. The compact fiber packaging system further comprises devices and methods for minimizing thermal gradients between fibers and for removing Waste heat from the system. Additionally, the available volume is further utilized by disposing equipment and materials for operation of the fibers inside a hollow center defined by the inner spool, between the nested spools, and adjacent the nested spools.

摘要： A detector 50 is included in a laser apparatus for generating a high energy laser beam to protect against the uncontrolled escape of the high energy laser beam from its prescribed optical path 14. The high energy laser beam proceeds along the optical path 14 and is directed to a work site 44 by a series of reflective surfaces in its path 26 and 30. The series of reflective surfaces function to change the path 14 of the beam 32 from the generating source to the work station 44. Associated with each of the reflective surfaces is a detector 50 which comprises a conductive frame 51 having a front face 52 and a back face 54. The back face 54 is equipped with a thermal sensor 60 which is positioned in a base portion 64 of the heat conductive frame 51. The detector is equipped with cooling means 58 and 66 for maintaining the threshold temperature. The sensor 60 which is affixed to the base portion 64 having a controlled thickness is preset at a threshold temperature such that in the event the reflective surfaces 26 or 30 breaks or otherwise fails permitting the beam 32 to strike the heat conductive frame 51 it would cause sudden rise in temperature of the sensor which would trigger the control circuit 69 to shut down the power supply 92 that energizes the high energy gain module 12.
