Crystals Laser Crystals Nd:YVO4

Introduction
Nd:YVO4 is one of the most efficient laser host crystal currently existing for diode laser-pumped solid-state lasers. Nd:YVO4 is an excellent crystal for high power, stable and cost dpss laser.

Low lasing threshold and high slope efficiency

Large stimulated emission cross-section at lasing wavelength

High absorption over a wide pumping wavelength bandwidth

Optically uniaxial and large birefringence emits polarized laser

Low dependency on pumping wavelength and tend to single mode output
