Frequently Asked Questions
LBO crystal is a nonlinear optical crystal that is used for frequency doubling, tripling, and quadrupling of laser beams. It has a broad transparency range and high damage threshold, making it suitable for various applications in laser instruments.
The transparency range of LBO crystal is from 160nm to 2600nm.
The effective SHG coefficient of LBO crystal is about three times that of KDP.
The maximum size of LBO crystal available is 30x30x30mm3 with a maximum length of 60mm.
DualBandAR-coating(DBAR) and BroadBandAR-coating(BBAR) are available for LBO crystal, depending on the application. Other coatings are also available upon request.
