LBO – Lithium triborate
04 Nov 2021
Due to the high damage threshold, wide transparency rage LBO – Lithium triborate crystals are mostly used for second harmonic generation (SHG) a.k.a. frequency doubling and third harmonic generation (THG). Crystals can be heated up for protection or performance stabilization and then they can be used in high power applications.
3photon leading advantage is high damage threshold of >10 J/cm² @ 355 nm (for single-band) AR coated LBO crystals, which allows great performance at very high intensities with high conversion effectivity.
