Product Description

 

LBO Lithium Triborate Crystal

 

LBO crystal is an excellent frequency doubling crystal, which is a widely used frequency doubling device at present. Its internal optical uniformity is good, the transmission band is relatively wide, and it has high matching efficiency and laser damage threshold.

 

Application

1. Double frequency

(1) Nd: YAG lasers for medical and industrial purposes;

(2) High power Nd: YAG and Nd: YLF lasers for scientific research and military purposes

(3) Pumping of Nd: YVO4, Nd: YAG, and Nd: YLF lasers

(4) Ruby, titanium sapphire, and Cr: LiSAF laser;

2. Triple frequency

(1) Nd: YAG and Nd: YLF lasers

(2) Optical parametric amplifier (OPA) and optical parametric oscillator (OPO)

(3) Second and third harmonic generation of high-power 1340nm Nd: YAP laser
