IPG Photonics offers single-frequency Cr:ZnSe/S continuous wave Mid-IR lasers. These lasers are offered as either fixed wavelength CL-SF or tunable CLT-SF models. The tunable range is from 1.9 to 2.6 μm, a fixed wavelength can be chosen in 1.9 - 3.0 μm range. Rapid tuning option is available. The lasers feature typical linewidth <1 MHz and TEM00 beam mode quality. The SF series Mid-IR lasers provide from up to 5 W output power. These lasers are pumped by IPG’s efficient and reliable erbium (1.6 micron) or thulium (1.9 micron) CW fiber lasers. Single-frequency Cr:ZnSe/S lasers are used in scientific and R&D applications such as high resolution spectroscopy, OPO pumping and free space communications.
