Nonlinear Crystals consist of β-barium borate (BBO) or lithium triborate (LBO) and feature anti-reflection (AR) coated surfaces with 20-10 surface quality. The surface flatness specifications for each crystal type are λ/8 and λ/10 for BBO and LBO options respectively. With damage thresholds up to 10 J/cm2 (@ 1064 nm, 10 ns 10 Hz), these crystals are ideal for are used ideal for frequency conversion of Ti:Sapphire and Yb:doped lasers.
TECHSPEC® Superpolished Substrates feature ≤1Å RMS surface roughness on both sized making these window substrates highly superior for reduced scatter or use with UV or high-power lasers. The low scatter of these substrates also makes them ideal substrate options for high-quality ion-beam sputtered (IBS) AR or reflective coatings. Additional applications for these superpolished windows include cavity-ring down spectroscopy, scatterometry, and UV laser eye surgery.
