CRYSTECH's Cr:YAG crystal enables passive Q-switching for 0.8–1.2µm lasers such as Nd:YAG, delivering high damage threshold (500–1000 MW/cm²) and room-temperature operation with no external drive electronics required. Well suited to short-pulse laser systems and laser ranging, with eye-safer emission and good thermal shock resistance. Read more...

CeNing Optics' non-polarizing beamsplitter cubes use dielectric coating only — no hybrid metallic layer — for negligible energy loss, with P-pol and S-pol transmission precisely controlled near 50% (±2%). N-BK7 substrate, λ/4 surface flatness, and 60-40 surface quality ensure consistent optical performance for narrow-wavelength applications. Read more...

CASTECH's Yb:CALGO laser crystal offers an extremely low quantum defect (1.5%) and high thermal conductivity (up to 6.9 W/m/K), making it well suited to high-power ultrafast lasers. Broad emission from 994–1050nm supports femtosecond pulse generation, with slope efficiency up to 55% under diode pumping. Standard dopant concentrations of 1–5 at.% available. Read more...

CeNing Optics' dielectric-coated laser mirrors deliver up to 99.9% reflectivity at a specific wavelength and angle of incidence (0° or 45°). Available in Commercial and Laser Grade tiers with N-BK7 or UV fused silica substrates, they suit laser systems requiring high-energy beam steering and precise wavelength-specific performance.

CeNing Optics' cylindrical plano-concave lenses in N-BK7 provide precise 1-D beam shaping for laser and imaging systems. Tight diameter and focal tolerances, λ/4 surface flatness, and fine 60-40 surface quality ensure consistent optical performance. Standard and custom diameters, wavelengths, and coatings are available to match your application. Read more...

Applying dielectric coating only instead of hybrid metallic coating, the non-polarizing beamsplitter will get no energy loss. The transmittance and reflectance can be precisely controlled to 50%.

Design only by dielectric coating only.
