BBO CRYSTAL

BBO - Beta-Barium-Borate crystal combines wide transparency range, large nonlinear coupling, wide thermal acceptance bandwidth, high laser damage threshold and good mechanical properties. It is typically used for second harmonic generation (SHG) from UV to about 2.1 m; broadly tunable optical parametric oscillators (OPOs) and amplifiers (OPAs); autocorrelation systems.
Maximum available size: 50 mm Dia x 70 mm thick.
