Nb. Singh et al., GROWTH AND CHARACTERIZATION OF GALLIUM SELENIDE CRYSTALS FOR FAR-INFRARED CONVERSION APPLICATIONS, Journal of crystal growth, 163(4), 1996, pp. 398-402
We have developed a method to synthesize large batch sizes of GaSe and
have grown single crystals by the Bridgman method. Our results show a
d value of 75 pV/m for GaSe. GaSe crystals were tested at a fluence o
f 1.6 J/cm(2) and 140 MW/cm(2) without damage. The 2 mm thick crystal
was used in a high-power test where a crystal with an AR coating was a
ble to operate at 30 kHz with an average power of 21 W into the crysta
l, equivalent to 32 kW/cm(2) CW in a 100 mu m spot.
