High Quality LBO Crystal with Large Aperture and High LDT

Short Description:

LBO (LiB3O5) is a kind of non-linear optical crystal with good ultraviolet transmittance (210-2300 nm), high laser damage threshold and large effective frequency doubling coefficient (about 3 times of KDP crystal). So LBO is commonly used to produce high power second and third harmonic laser light, especially for ultraviolet lasers.
