摘要： A solid state laser amplifier architecture in which multiple zig-zag slab laser amplifiers (50) are stacked together, side-pumped using a common pump source (52, 54), and cooled with a common cooling system. The stack of zig-zag slabs (50) produces an array of sub-beams (62) that can be combined coherently into a single composite output beam. Variations in pump power absorption through the stack are mitigated by selection of doping levels for the slabs (50). The composite output beam is sufficiently symmetrical to be directed through conventional optics of circular cross section. Multiple stacks may be arranged in a two-dimensional array to obtain even higher output powers.

摘要： A system and method for laser light amplification provides amplification of a laser light emitted from a laser light source as low-amplification seed laser light signal. The low-amplification seed laser light signal is transmitted to an amplification component. The amplification component amplifies the low-amplification seed laser light signal by stimulating emissions of the population inversion provided by a pumping diode to generate an amplified laser light signal. The system and method further directs the amplified laser light signal to an output destination. The result of the present invention is a system and method of operation providing higher pulse rates, improved pointing stability, and optionally variable pulse rates for a variety of uses, including for non-destructive laser ultrasonic testing of materials.

摘要： A laser device (10) which may be used as an oscillator or amplifier comprising a chamber (12) having a volume formed therein and a gain medium comprises solid-state elements (14) containing active laser ion distributed within the volume. A cooling fluid (16) flows about the solid-state elements and a semiconductor laser diode (18) provides optical pump radiation into the volume of the laser chamber (12) such that laser emission from the device passes through the gain medium (14) and the fluid (16). The laser device (10) provides the advantages of a solid-state gain medium laser (e.g., diode-pumping, high power density, etc.), but enables operation at higher average power and beam quality than would be achievable from a pure solid-state medium.
