Hot Sale for Ho,Cr,Tm Doped Yttrium Aluminium Garnet - Yb:YAG Crystals – Dien

Yb:YAG is one of the most promising laser-active materials and more suitable for diode-pumping than the traditional Nd-doped systems. Compared with the commonly used Nd:YAG crsytal, Yb:YAG crystal has a much larger absorption bandwidth to reduce thermal management requirements for diode lasers, a longer upper-laser level lifetime, three to four times lower thermal loading per unit pump power. Yb:YAG crystal is expected to replace Nd:YAG crystal for high power diode-pumped lasers and other pot...

ZGP (ZnGeP2) Crystals for THz and middle infrared OPO and OPG/OPA

DIEN TECH offers ZnGeP2 ZGP crystals with super low absorption and high damage threshold. Large size available upon request. Zinc-Germanium Diphosphide (ZnGeP₂, ZGP) single crystals knowing as the king of nonlinar crystals, have super high nonlinear coefficient , it is a highly-effective nonlinear optical material for the middle IR, as well as terahertz range( low absorption at 1um). ZnGeP₂ crystals have positive birefringence which allows one to carry out the phasematched parametric frequency conversion of optical radiation in all the ranges of their background transparency spectrum from 0.75 to 12.0 µm. ZnGeP2 has the largest non-linear optical coefficient and a relatively high laser damage threshold. It was successfully used in the following applications: up-conversion of CO2 laser light to near IR range via mixing with 1.06 mm; sum frequency generation of CO and CO2 laser radiation; efficient SHG of pulsed CO, CO2 (49% efficiency at 1 GW/cm2 intensity of 2 ns pulses, 9.52 mm wavelength) and chemical DF-laser, OPO light generation in mid infrared when pumped by erbium and holmium lasers.
Infrared ZnGeP2 (ZGP) crystals

Infrared ZnGeP2 (ZGP) crystals have transmission band edges at 0.74 and 12 µm. However their useful transmission range is from 1.9 to 8.6 µm and from 9.6 to 10.2 µm. These crystals have the largest nonlinear optical coefficient and relatively high laser damage threshold. ZGP crystals can successfully be used in diverse applications: Up-conversion of CO2 and CO laser radiation to near IR range via harmonics generation and mixing processes, efficient SHG of pulsed CO, CO2 and chemical DF-laser, and efficient down conversion of Holmium, Thulium and Erbium laser wavelengths to mid infrared wavelength ranges by OPO process.
