Er,Cr YSGG Provides An Efficient Laser Crystal
Due to the variety of treatment options, dentine hypersensitivity (DH) is a painful disease and a clinical challenge. As a potential solution, high-intensity lasers have been researched. This clinical trial was designed to examine the effects of Er:YAG and Er,Cr:YSGG lasers on DH. It was randomized, controlled, and double-blind. The 28 participants in the study group all satisfied the requirements for inclusion. Sensitivity was measured using a visual analogue scale before therapy as a baseline, immediately before and after treatment, as well as one week and one month following treatment.

ZnGeP2 — An Saturated Infrared Nonlinear Optics
Due to possessing large nonlinear coefficients (d36=75pm/V), wide infrared transparency range(0.75-12μm), high thermal conductivity(0.35W/(cm·K)), high laser damage threshold (2-5J/cm2)and well machining property, ZnGeP2 was called the king of infrared nonlinear optics and is still the best frequency conversion material for high power, tunable infrared laser generation.

AgGaS2 — Nonlinear Optical Infrared Crystals
AGS is transparent from 0.53 to 12 µm. Although its nonlinear optical coefficient is the lowest among the mentioned infrared crystals, high short wavelength transparency edging at 550 nm is made use of in OPOs pumped by Nd:YAG laser; in numerous difference frequency mixing experiments with diode, Ti:Sapphire, Nd:YAG and IR dye lasers covering 3–12 µm range; in direct infrared countermeasure systems, and for SHG of CO2 laser.
