These Birefringent Crystals are a
positive uniaxial birefrigent single crystal. Dayoptics select the
best quality quartz, which has min inclusions and refractive index
variation as the raw material of our components. Quartz is commonly
used for high damage threshold waveplates.

These Laser Crystals are 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.
Our range of NLO Crystals are an
excellent non-linear crystal for frequency-doubling (SHG) of
Visible and Near IR laser light, OPO/OPG/OPA pumped by ultrafast
pulses of wavelengths in the Near IR to UV, and sum-frequency
mixing (SFM) into the Visible to the deep UV. BBO is one of the few
practical crystal for use below **0 nm in SHG and SFM.
NLO Crystals has broad tunability, high damage threshold, and high
efficiency. BBO's small acceptance angle requires a very good beam
quality and its large walkoff results in output beams that are very
elliptical or slit-like. Type I is usually much more efficient than
type II operation. BBO can not be used for NCPM (temperature tuned)
application.
BBO is very good for tunable laser sources, such as ultrafast
Ti:Sapphire or dye lasers. And it is also widely used for SHG, 3HG,
4HG, and autocorrelation of femtosecond and picosecond Ti:Sapphire
lasers; SHG, 3HG, 4HG, 5HG of YAG lasers at ***4 nm and ***0 nm to
yield output of ******0nm; SHG of tunable dye or solid-state laser
sources from ******0 nm to yield output of ******5 nm, SFM of dye
laser and YAG harmonics to yield output of ******0 nm; DFM
(difference-frequency mixing) from the Visible to the IR range up
to over ***0 nm; OPO pumped with SHG or 3HG of YAG or Ti:Sapphire
with an output range of *******0 ; Intracavity SHG of Argon ion
lasers (**8, **4 nm).
