LBO Crystal

 

Applications:
Harmonics of high power Nd:YAG and Nd:YLF lasers for Medical, industrial, R&D and military applications
Frequency doubling (SHG) of Ti:Sapphire, Alexandrite, Cr:LiSAF lasers, and diode laser pumped Nd:YVO4, Nd:YAG and Nd:YLF lasers
Optical parametric amplifiers (OPA) and oscillators (OPO) pumped by Excimer lasers of Nd:YAG lasers
Frequency doubling (SHG) and tripling (THG) of high power Nd:YAP laser at 1340nm
 
Advantages:
Wide transparency,.high nonlinear coupling, good chemical and mechanical properties
Type I and type II non-critical phase-matching (NCPM) over a wide wavelength range.
High damage threshold(18.9 GW/cm2 for a 1.3ns laser at 1054nm)
Wide acceptance angle and small walk-off angle
High optical quality (homogeneity10-6/cm)

NOTE
LBO has a very low susceptibility to moisture. Users are advised to provide dry conditions for both use and preservation of LBO.
LNG engineers can select and design the best crystal for you if parameters of your laser are provided, for example, energy per pulse, pulse width and repetition rate for a pulsed laser, power for a cw laser, laser beam diameter, mode condition, divergence, wavelength tuning range, etc.
LNG provides mounts and sealed housing for LBO crystals, glass coating witness when customers need.
LNG provides oven and temperature controller for LBO of temperature matching.
