AR/HR/PR coatings are available at your specified wavelength.
Be sure to wear laser safety goggles when checking optical path and adjusting optical axis.
CLBO is relatively soft and therefore requires precautions to protect its polished surfaces.
When angle adjusting is necessary, keep in mind that the acceptance angle of CLBO is small.
