LBO Nonlinear Crystals
LBO(Lithium Triborate LiB305) is a newly developed nonlinear optical crystal.It is unique in many aspects,especially its wide transprency range,moderately high nonlinear coupling,high damage threshold and good chemical and mechanical properties.
LBO Crystal Advantages
1. Wide transparency,. High nonlinear coupling, good chemical and mechanical properties
2. Type I and type II non-critical phase-matching (NCPM) over a wide wavelength range.
3. High damage threshold(18.9 GW/cm2 for a 1.3ns laser at 1054nm)
4. Wide acceptance angle and small walk-off angle
5. High optical quality (homogeneity≈10-6/cm)
LBO Crystal Applications:
1. High power Nd:YAG and Nd:YLF lasers for R&D, military applications, Frequency-tripling (THG) and Medical, Industrial.
2. Ti:Sapphire, Alexandrite and Cr:LiSAF lasers.
3. Diode laser pumped Nd:YVO4, Nd:YAG and Nd:YLF lasers.
4. Optical parametric amplifiers (OPA) and oscillators (OPO) pumped by Excimer lasers and harmonics of Nd:YAG lasers.
5.Frequency doubling (SHG) and tripling (THG) of high power Nd:YAP laser.

NOTE:
1. LBO has a very low susceptibility to moisture.
2. Users are advised to provide dry conditions for both use and preservation of LBO.
3. WTS 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.
4. WTS provides mounts and sealed housing for LBO crystals.
