KBBF (Potassium Beryllium Fluoroborate) – Nonlinear Crystal – Customized Products

KBe2BO3F2 (Potassium Beryllium Fluoroborate), abbreviated as KBBF, is a uniaxial crystal system with R32 space group and has a wide transmission range with a UV cut-off edge of 150 nm. Compared to crystals such as BBO and LBO, KBBF crystals also have a large thermal conductivity (LBO: 3.5 W/mK, KBBF: ~2.5 W/mK), indicating that the crystal has a high laser damage threshold. For example, using an Nd:YAG laser (1064 nm, 80 ps, 1 kHz), the crystal has optical damage thresholds as high as 900 GW/cm2 and 72 J/cm2, which is nearly an order of magnitude greater than the anti-laser damage threshold of a BBO crystal under the same conditions. KBBF crystal is one of the crystals that can achieve multiplicative output of deep UV lasers below 200 nm.
