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
