Aries-2™ Mid-IR Laser: Powerful Fixed Wavelength, Narrowband Output

The Aries-2 series consists of fixed-wavelength, narrowband mid-IR lasers, offering an average output power reaching 1 W. Featuring a highly durable and stable resonator design, the Aries-2 laser ensures excellent control over linewidth and maintains wavelength stability, even under changing environmental conditions. Available with a variety of quantum cascade laser chips, the Aries-2 can be tailored during manufacturing to meet diverse application requirements.

Included with Aries-2 systems is the SideKick laser controller, which provides versatile and accurate adjustments of laser output power, temperature, and pulse settings.
