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

Diffusion bonding crystals These Diffusion Bonded composite crystals are used to effectively decrease heat effect of Solid-State High-Power Laser.
High damage threshold
Improve beam quality
Decrease thermal effect
Improve efficiency
Compact size
Composite laser rod is a crystal consisting of two, three or more parts with different dopant level. Usually, doped and undoped material used.
Dopant level and rod configuration can vary as well as the number of parts. It can have different wedged structure, Brewster angles, etc.
