Mid-IR Crystals
IPG Photonics offers Cr2+, Co2+ and Fe2+ diffusion-doped ZnSe/ZnS polycrystalline ceramic gain materials and saturable absorbers. IPG’s proprietary fabrication process allows low cost mass production of a large variety of iron and chromium doped ZnSe/ZnS crystals with low losses, uniform distribution of transition metal dopant excellent reproducibility and reliability. The optical and spectroscopic characteristics of these crystals make them the gain materials of choice for compact and efficient laser sources operating in 1.8 to 6 microns range.
Chromium and iron doped ZnSe/S lasers are promising for spectroscopy, sensing, medical and defense applications, as well as for seeding or pumping middle-infrared optical parametric oscillators.
Mid IR Gain Media
Cr2+:ZnSe and Cr2+:ZnS Laser Active Materials
The unique combination of available pump sources (Er-fiber, Tm fiber, telecom or InP diodes, Er:YAG/YLF; Tm: YAG/YLF), technological (low cost ceramic material), optical and spectroscopic characteristics (ultrbroadband gain bandwidth, high st product and high absorption coefficients) make them the gain materials of choice when one needs a compact system with continuous tunability at 300 K over 1.8-3.4 mm, output powers up to 30 W and high (up to 70%) conversion efficiency.
