摘要： A compact diode pumped laser including a nonuniform, single- or double-sided diode pumped laser head (11, 31) and a polarization output coupled (POC) resonator (70). The POC resonator (70) employs reflections from two opposing uncrossed roof prism mirrors (61, 71) to produce a uniform near field and far field beam with diffraction or near diffraction limited quality. The single laser head (11) particularly includes a laser rod (21), a sapphire envelope (19) located about the rod (21), an area (17) of antireflection coating located on the sapphire envelope (19) between the rod (21) and the diode array (15), and a high reflectivity nickel-plated indium layer (18) located on the sapphire envelope (19) on the surface thereof outside of the area (17) of antireflection coating.

The laser includes at least one diode pump source supplying a pump beam to the laser crystal, producing a thermal lens in the laser crystal.

摘要： A high average power, high brightness solid state laser system. We first produce a seed laser beam with a short pulse duration. A laser amplifier (24) amplifies the seed beam to produce an amplified pulse laser beam which is tightly focused to produce pulses with brightness levels in excess of 10 Watts/cm . Preferred embodiments produce an amplified pulse laser beam having an average power in the range of 1 kW, an average pulse frequency of 12,000 pulses per second with pulses having brightness levels in excess of 10 Watts/cm at a 20 micrometers diameter spot which may be steered rapidly to simulate a larger spot size. Alternately, a kHz system with several (for example, seven) beams (from amplifiers arranged in parallel) can each be focused to 20 micrometers and clustered to create effective spot sizes of 100 to 200 micrometers. These beams are useful in producing X-ray sources for lithography.

摘要： Method for making a distortion-compensating phase-adjustment element for a laser. One type of distortion to be compensated for is heat distortion. Also described is a method for making a custom phase-conjugating diffractive mirror for a laser resonator comprising the steps of: (a) choosing a specified beam mode profile a1(x,y); (b) calculating the mode profile b(x',y') which is a value of the specified beam a1(x,y) that is propagated to the reflection surface of the diffractive mirror and (c) calculating mirror reflectance t(x',y') which reflects phase conjugate of b(x',y') and corrects for distortions such as heat. A method for fabricating such a mirror is shown. Another aspect of the invention is the addition of a phase adjusting element into a laser resonator, and compensating for the addition of a phase adjusting element in the design of other phase-adjusting elements such as the mirrors and correcting for distortions such as heat.

摘要： This invention relates to a diode pumped slab laser in the form of a slab (1) where two opposite faces (2, 3) are adapted to receive pumping radiation with the faces being cut at the Brewsters angle at one end (6, 7) to provide entrance/exit faces for the lasing radiation. The laser radiation beam follows a zig-zag path in the slab (1) and is contained within the slab by total internal reflection. The laser slab (1) is contained within an optical cavity which results in the laser beam completing a double zig-zag beam path. The design results in good pump/mode matching, mitigates thermally induced birefringence problems, overcomes amplified spontaneous emission problems, requires no coatings or curved surfaces, and is easy and relatively inexpensive to make. The slab (1) can be used within both Quasi-CW and CW modes.

摘要： A system includes a master oscillator (102) configured to generate a low-power optical beam (808). The system also includes a planar waveguide (PWG) amplifier (104) configured to amplify the low-power beam into a high-power output optical beam (116, 806), where the PWG amplifier has a larger dimension in an unguided direction and a smaller dimension in a transverse guided direction. The system further includes an adaptive optic (108, 202, 302, 502) configured to pre-distort the low-power optical beam substantially along a single dimension prior to injection of the low-power optical beam into the PWG amplifier in order to compensate for thermal-based distortions created by the PWG amplifier. The single dimension represents the unguided direction. In addition, the system includes a feedback loop configured to control the adaptive optic.
