Solid state blue-green laser with high efficiency laser pump

Patent ·
OSTI ID:7094025
A high efficiency, high power blue-green laser is described which is capable of providing short pulses useful for underwater communication and detection systems. To provide the desired blue-green lasing, a solid state laser is pumped by a matched high-efficiency laser having relatively long duration output pulses. Q-switching of the solid state laser is used to shorten the duration and increase the peak power of the pulses. Material found especially useful for practice of the invention are Holmium (+3) and Praseodymium(+3) as the solid state laser and a dye laser pumped by a mercury capillary lamp as the pumping laser.
