IPG Photonics offers Cr:ZnSe/S continuous wave Mid-IR hybrid lasers in 1.9 to 3 micron wavelength range. These lasers are offered at either a fixed customer selected wavelength (CL Series) or CW tunable (CLT Series). Standard and rapid tuning options are available. The output power is up to 150 W (fixed) and 100 W (tunable), and typical linewidth is 0.1 to 1 nm. These hybrid solid state lasers are pumped by IPG’s efficient and reliable erbium (1.6 micron) or thulium (1.9 micron) CW fiber lasers. Cr:ZnSe/S CW fixed and tunable wavelength lasers are used in a range of applications including spectroscopy, Mid-IR OPO pump source, environmental monitoring, medical applications and plastics material processing.

* Customer can select a fixed center wavelength for CL models or specify a tuning range for tunable wavelength CLT models.
** Standard linewidth of narrow line CL and CLT lasers is 0.1 to 1 nm, typical linewidth is < 0.5 nm. If you have special need regarding the linewidth, please discuss it with your IPG representative. Single-frequency CL-SF and CLT-SF models are also available.
*** Custom output powers are available upon request. Output power may be limited by wavelength selection.
**** All tunable lasers are motor-driven and computer controlled. An external wavelength meter must be used to monitor the output wavelength.
Rapidly tunable (swept) models allow scanning the entire tuning range with acquisition rate of up to 1000 spectra per second. These laser models are designed for characterizing broad spectral features such as absorption spectra of polymers.
***** Beam diameter and divergence may be adjusted to meet customer specifications.

* Pump laser model depends on the combination of parameters. The pump laser can be randomly or linearly polarized. Randomly polarized pumps are less expensive, while linearly polarized pumps provide a higher absorption efficiency, resulting in slightly lower heat dissipation requirements for the laser head. For demanding scientific applications, single-frequency fiber laser pumps may be preferred for lower RMS power noise.
