- Kilohertz AgGaSe2 optical parametric oscillator pumped at 2 ?mP. A. Budni, M. G. Knights, E. P. Chicklis, and K. L. Schepler Optics Letters, Vol. 18, Issue 13, pp. 1068-1070 (1993)A high-repetition-rate high-average-power AgGaSe2 doubly resonant optical parametric oscillator has been demonstrated by using a 2-?m pump laser operating at 2.5 and 5 kHz. Energy conversion and slope efficiencies of 23% and 32%, respectively, were achieved. Sustained average power outputs as high as 740 mW were measured. Evidence of optical parametric oscillator output saturation and damage site formation at the crystal output face are effects attributed to thermal lensing in our AgGaSe2 crystal.http://www.opticsinfobase.org/ol/abstract.cfm?uri=ol-18-13-1068Optical constants of AgGaSe2 (Silver gallium selenide)http://refractiveindex.info/legacy/?group=CRYSTALS&material=AgGaSe2Second harmonic generation and infrared mixing in AgGaSe2http://scitation.aip.org/content/aip/journal/apl/24/2/10.1063/1.1655096

- Generation of wide terahertz radiation using bulk and quasi-phase-matched GaAs crystal - request a quote for GaAs crystalAuthor(s): Baolong Yu, Naibing Ma, Min-Yi Shih, Alexander V. Parfenov, Physical Optics Corp. (United States)Physical Optics Corporation (POC) studied intense terahertz (THz) generation through optical rectification in bulk low-temperature growth GaAs (LG-GaAs) and quasi-phase-matched orientation pattern GaAs (OP-GaAs). POC performed simulations based on one-dimensional coupled propagation equations of THz and optical fields and conducted experimental tests. The results show that a LG-GaAs crystal with 0.5mm-thick under the excitation of a compact all-fiber femtosecond laser (76 MHz, 100 fs, 100 mW, 800 nm) can generate wide frequency range from 0.1 to 8.2 THz. The enhanced conversion efficiency was found for OP-GaAs crystal that can generate an average THz power of several milliwatts. Both theoretical and experimental results show that average THz output power is proportional to the energy fluence of the excitation source rather than the laser power for ultra-short pulse source. These achievements provide an effective approach to increase THz output power.http://www.dmphotonics.com/GaAs_crystal/GaAs%20crystal.htm
