Nd YVO4 High Slope Efficiency For Diode Laser-pumped Solid-state Lasers
Products Description:
Nd doped Yttrium vanadate (Nd:YVO4) is the most efficient laser
host crystal for diode pumping among the current commercial laser
crystals, especially for low to medium power. This is mainly due to
Nd:YVO4' s absorption and emission features which surpass Nd:YAG.
Pumped by laser diodes, Nd:YVO4 crystal has been incorporated with
NLO crystals (KTP, BBO or BIBO ) to frequency-shift the output from
the near infrared to green, blue, or even UV. This incorporation to
construct all solid state lasers is an ideal laser tool that can
cover the most widespread applications of lasers, including
machining, material processing, spectroscopy, wafer inspection,
light displays, medical diagnostics, laser printing, and data
storage, etc. It has been shown that Nd:YVO4 based diode pumped
solid state lasers are rapidly occupying the markets traditionally
dominated by water-cooled ion lasers and lamp-pumped lasers,
especially when compact design and single-longitudinal-mode outputs
are required
APPLICATION:
- Industrial Laser
- Medical Laser
- Laser show system
- Mainly used for end-pumped CW and QCW low and medium power solid state lasers.
ADVANTAGE:
- Low lasing threshold and high slope efficiency
- Large stimulated emission cross-section at lasing wavelength
- High absorption over a wide pumping wavelength bandwidth
- uniaxial and large birefringence, emits polarized laser
- Low dependency on pumping wavelength and easy to get single mode output
