Aries-2™ Mid-IR Laser

High Power, Fixed Wavelength, Narrowband Output

The Aries-2 series is a family of fixed-wavelength, narrowband mid-IR lasers with an average output power of up to 1 W. The Aries-2 laser has an extremely robust and stable resonator structure providing users with superb linewidth control and wavelength stability, especially as environmental conditions vary. With a wide selection of quantum cascade laser chips available, Aries-2 can be factory-configured to suit different application needs.

Aries-2 systems include a SideKick laser controller, which gives you flexible, precise control of laser output power, temperature, and pulse parameters.


Features & Benefits:
