CL-SF/CLT-SF
Product Description
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 between
1.9-2.6 μm with a custom selected central
wavelength. The lasers feature a linewidth range
of <1 MHz and TEM00 beam mode quality. The SF
series Mid-IR lasers provide up to 5 W of output
power. These lasers are pumped by IPG’s efficient
and reliable erbium (1.6 μm) or thulium (1.9 μm)
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.
