Nd:YVO4 Crystals, 2%Doping, 3mm Length, AR Coating

Neodymium-doped yttrium vanadate (Nd:YVO4) crystal is one of the effective laser host crystals. Its large stimulated emission cross section at the lasing wavelength, high absorption coefficient and broad absorption bandwidth at the pumping wavelength, high laser-induced damage threshold, and good physical, optical and mechanical properties make it a high-power, stable and Excellent crystal for the cost. We offer various sizes of Nd:YVO4 crystals.

Spec Sheet

Features And Benefits

1. High absorption and gain cross section 2. Strong polarization-dependent absorption and emission spectra (preferably π-polarized) 3. Shorter (compared to Nd:YAG) upper-state lifetime 4. High optical quality and large diameter ingots obtained by Czochralski growth

Application

Nd:YVO4 crystals are ideal for passively mode-locked lasers with high pulse repetition rates. Nd:YVO4 is more suitable as the active medium for Q-switched lasers with high pulse repetition rate and CW lasers with lower lasing threshold.
