The Q-TUNE-IR tunable DPSS laser from Quantum Light Instruments has everything you need to enhance and simplify your Infrared Spectroscopy application. This compact, turnkey system provides a user-friendly web interface, giving you the freedom to control the laser remotely from any computer or smart phone browser without having to download or install software. The advanced, microprocessor-controlled operation allows for automated self-optimization, self-calibration, and hands-free tuning at the click of a button. So, you don’t have to be a laser expert to achieve great results.

The Q-TUNE-IR uses an Optical Parametric Oscillator (OPO) to produce tunable wavelength in 1380 – 4500 nm range with a linewidth less than 10 cm-1, achieving > 6.5mJ of pulse energy @ 3500nm for the F-10 configuration (> 2mJ @ 3500nm for C-10) with a 10Hz repetition rate. A broadband version with linewidth up to 200 cm-1 is also available by request.  The Q-TUNE-IR requires little maintenance, with all laser electronics integrated into the housing, including an air-cooling system, eliminating the need for chillers, or large power supplies, all while providing a guaranteed pump diode lifetime greater than 2 giga-shots.
