LBO Lithium Triborate Nonlinear Crystals
Lithium Triborate - LiB3O5
GAMDAN Optics, Inc. LBO Crystal Boule
An exceptional high laser damage threshold and excellent physical properties make LBO an ideal candidate for high power green-blue UV conversion of solid state and fiber lasers. As laser pulses shorten and average power continues to increase, the surfaces of the LBO crystal often see the highest power density. Surface damages and the resulting loss of output power and the distortion of the beam caused by localized absorption resulting in thermal instability are some of the major issues in high power applications.
Small traces of contaminants during the growth and fabrication process can lead to these major breakdown issues, especially in the UV. Our bulk super low absorption crystal, combined with our proprietary UV-grade super polish process is critical for highest damage threshold and stability in long term operations.
CALIBRATED ABSORPTION <10 PPM/CM
Exceptionally low calibrated IR absorption (<10ppm/cm) as measured by PCI (Photo-thermal Common-Path Interferometry). (*UV absorption analysis is available upon request)
