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.
