Edmund Optics , a supplier of optical components, has launched non-linear crystals, with very high laser damage thresholds (LIDT) and Techspec superpolis substrates, which are characterized by extremely low surface roughness; both are ideal for high-power laser applications.
Non-linear crystals are made up of barium β-borate (BBO) or lithium triborate (LBO) and have anti-reflective treated surfaces (ARs) with a surface quality of 20-10. The surface flatness specifications are 8/8 for the BBO and 10 for the LBO. With damage thresholds of up to 10 J/cm2 (at 1064 nm, 10 ns 10 Hz), these crystals are suitable for the frequency conversion of Ti:saphir and Yb doped lasers.
Techspec superpolis substrates have a surface roughness RMS ≤1 on both sides, making these window substrates highly superior for reduced dispersion or use with UV or high-power lasers. The low dispersion of these substrates also makes them ideal substrates for high-quality AR or reflective treatments obtained by ion spraying (IBS). Other applications of these superpolis windows include optical cavity spectroscopy, scatterometrics and UV laser eye surgery.
