摘要： An slab CO2 laser includes spaced-apart elongated slab electrodes. A lasing gas fills a discharge gap between the electrodes. An RF power supply is connected across the electrodes and sustains an electrical discharge in the lasing gas in the discharge gap. Either one or two ceramic inserts occupy a portion of width of the electrodes and in contact with the electrodes. A discharge gap is formed between the portions of the width of the electrodes not occupied by the insert or inserts. Provision of the ceramic insert or inserts increases the resistance-capacitance (RC) time constant of the electrode impedance by increasing the capacitive component of the time constant. This hinders the formation of arcs in the discharge, which, in turn enables the inventive laser to operate with higher excitation power or higher lasing-gas pressure than would be possible without the dielectric insert. The ceramic insert also decreases the difference in impedance of the electrodes with and without a discharge. This leads to a better-behaved discharge, and a discharge that is easier to light.

摘要： A slab laser includes two elongated electrodes arranged spaced apart and face-to-face. Either one or two slabs of a solid dielectric material extend along the length of the electrodes between the electrodes. A discharge gap is formed either between one of the electrodes and one dielectric slab, or between two dielectric slabs. The discharge gap is filled with lasing gas. A pair of mirrors is configured and arranged to define a laser resonator extending through the gap. An RF potential is applied across the electrodes creating a gas discharge in the gap, and causing laser radiation to circulate in the resonator. Inserting dielectric material between the electrodes increases the resistance-capacitance (RC) time constant of the discharge structure compared with the RC time constant in the absence of dielectric material. This hinders the formation of arcs in the discharge, which enables the laser to operate with higher excitation power, higher lasing gas pressure, and higher output power than would be possible without the dielectric inserts.

摘要： The apparatus of the present invention significantly improves the optical intensity induced damage limit of optical quality crystals, and in particular crystals used in the conversion of laser radiation at a specific wavelength to another wavelength or other wavelengths through non-linear interaction of the input laser radiation with the optical crystal medium. In accordance with the present invention, passive optical elements are positioned at the laser beam exiting and entrance surfaces of the active optical element. The surfaces of the passive optical elements are placed up against respective exiting and entrance surfaces of the active optical element. Since the optically transparent passive optical elements have higher mass than optical coatings, they provide vastly superior cooling, and therefore, considerably higher laser damage threshold for the surfaces. Higher damage thresholds results in a significant increase in the performance, reliability, and failure damage safety margin while reducing size and cost of high intensity laser systems and subsystems that utilize active optical elements.
摘要翻译：本发明的装置显着改善了光学质量晶体的光强度诱发的损伤极限，特别是通过输入激光辐射的非线性相互作用将特定波长的激光辐射转换成另一波长或其它波长的晶体与光学晶体介质。根据本发明，无源光学元件位于离开激活光学元件的入射表面的激光束处。无源光学元件的表面被放置在相对于有源光学元件的相应出射和入射表面上。由于光学透明无源光学元件具有比光学涂层更高的质量，因此它们提供了非常优异的冷却，因此提供了相当高的表面的激光损伤阈值。更高的损伤阈值导致性能，可靠性和故障损伤安全裕度的显着增加，同时降低了使用有源光学元件的高强度激光系统和子系统的尺寸和成本。

摘要： A new resonator concept which is especially useful in chemical laser applications is disclosed. A ring end mirror, a conical folding mirror and a circular end mirror are combined to form an unstable resonator including a radial direction propagation having a gain medium region and a region of axial direction propagation. Alternate embodiments of the invention include the use of nonreflective fins in the region containing the working medium to suppress superfluorescence and an aerodynamic window to keep depleted working medium out of the path of the resonant beam.
