N. Mackinnon et Bd. Sinclair, A LASER-DIODE ARRAY PUMPED, ND-YVO4 KTP, COMPOSITE-MATERIAL MICROCHIPLASER/, Optics communications, 105(3-4), 1994, pp. 183-187
Fifty milliwatts of green (532 nm) fundamental spatial mode light have
been generated by a continuous wave, frequency doubled microchip lase
r, consisting of a 0.5 mm thick piece of Nd:YVO4 in intimate optical c
ontact with a 2 mm thick piece of KTP, and pumped by a laser diode arr
ay immediately behind the microchip. The initially nominally plano/pla
no cavity produced a near diffraction limited fundamental output beam
at all pump powers.
