Coating Specifications
1.
Protective Coating (P-coating)
Dream
Lasers provide the protective coating which
can prevent the polished surfaces of BBO from exposure
to moisture, considering the fact the polished surfaces
are very easy to be fogged in humid air due to its low
hygroscopic susceptibility. P-coated BBO with a mount
is much simpler and better to use than BBO with housing.
2. Anti-Reflective Coatings (AR-coatings)
Dream
Lasers can manufacture and supply single-band,
dual-band and broad-band AR-coatings for BBO applications
(extracavity and intracavity SHG, THG, 4HG, SFG, OPO,
etc.), featured by high damage threshold,. low reflectance,
anti-moisture and long durability. Typical AR-coatings
and residual reflectivities are listed as following
for reference. AR-coatings at other wavelengths are
available upon customers' requests.

Note
1. BBO
is soft and therefore the protection of its polished
surfaces requires precautions.
2. BBO
has a low susceptibility to moisture. The user is advised
to provide dry conditions for both use and preservation
of BBO.
3. Keep
in mind that the acceptance angle of BBO is small, when
angle adjusting is necessary.
4. Dream
Lasers can design and select the best crystal
for you if the parameters of your laser are provided
(such as: energy per pulse, pulse width and repetition
rate for a pulsed laser, power for a cw laser, mode
condition, divergence, laser beam diameter, wavelength
tuning range, etc)
