Edmund Optics Releases New Laser Optics for High-Power Laser Applications

Posted May 05, 2021

Edmund Optics, a provider of optical components, continuously expands its product offering to reflect market developments and customer needs. They add new products month to better serve the industry. EO has released Nonlinear Crystals, which have high laser-induced damage thresholds (LIDTs), and TECHSPEC Superpolished Substrates, which have extremely low surface roughness, both of which are ideal for high-power laser applications.

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 (@ 1064nm, 10ns 10Hz), these crystals are ideal for frequency conversion of Ti:Sapphire and Yb:doped lasers.

TECHSPEC Superpolished Substrates feature ≤1Å RMS surface roughness on both sizes, 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.
