CERTIFICATE OF CONFORMITY (sample)
b-Barium-Borate crystals (BBO) combine wide transparency range, large nonlinear coupling, wide thermal acceptance bandwidth, high laser damage threshold and good mechanical properties.
Applications:
Second harmonic generation (SHG) from UV down to about 2.1 mm
Broadly tunable optical parametric oscillators (OPOs) and amplifiers (OPAs)
