Nd:YVO4

Quantity : 999

Nd: YVO4 crystal is one of the most efficient laser host crystal currently existing for diode laser pumped solid state lasers. Its large stimulated emission cross-section at lasing wavelength, high absorption coefficient and wide absorption bandwidth at pump wavelength, high laser induced damage threshold as well as good physical, optical and mechanical properties make Nd: YVO4 an excellent crystal for high power, stable and cost effective diode pumped solid-state lasers.

Main Features

• Low lasing threshold and high slope efficiency

• Low dependency on pump wavelength

• Large stimulated emission cross-section at lasing wavelength

• High absorption over a wide pumping wavelength bandwidth

• Optically uniaxial and large birefringence emits polarized laser

Typical Applications

• For Single-longitudinal-mode output and compact design

• Diode laser-pumped Nd: YVO4 compact laser and its frequency-doubled green, red or blue laser will be the ideal laser tools of machining, material processing, spectroscopy, wafer inspection, light show, medical diagnostics, laser printing and other most widespread applications
