Gc. Bhar et al., CHARACTERIZATION OF BIAXIAL CRYSTALS FOR TANGENTIALLY PHASE-MATCHED FREQUENCY-CONVERSION, Applied physics. B, Photophysics and laser chemistry, 56(5), 1993, pp. 327-330
Ultraviolet radiation has been generated by tangentially phase-matched
sum-frequency mixing in biaxial L-arginine phosphate (LAP) crystal fo
r the first time using Nd:YAG output at 1064 nm and Rh 6G dye laser ou
tput at 560 nm as the two input sources. Characterization has also bee
n made of such a cheap, biaxial crystal for its possible use in device
s for tangentially phase-matched short wavelength generation. If the c
rystal is of proper cut, thickness and quality so that its maximum cap
ability can be exploited it can replace the potassium dihydrogen phosp
hate (KDP) group of crystals for various applications.
