Tunable Lasers

What are Tunable Lasers?

Tunable DPSS lasers use an Optical Parametric Oscillator (OPO) to produce tunable wavelengths in the 410 – 2300 nm range.

This laser offers nanosecond (ns) pulse widths and a variable repetition rate up to 100 Hz, with up to 5 mJ pulse energy in the visible range.

With its tunability, this laser is the perfect coherent light source for temporally resolved spectroscopy, metrology, photoacoustic imaging, and remote sensing.

Q-TUNE-IR Series

Q-TUNE-IRThe Q-TUNE-IR series is the perfect high peak power, coherent, DPSS light source for researchers working with infrared spectroscopy applications. This series uses an Optical Parametric Oscillator (OPO) to produce tunable wavelength in the 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. 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. 

Q-TUNE Series


The Q-TUNE series is a highly efficient, tunable wavelength laser designed for researchers working with temporally resolved spectroscopy, metrology, photo-acoustic imaging, and remote sensing applications. This laser uses an optical parametric oscillator (OPO) to produce a tunable wavelength range of 410-2300 nm with a linewidth narrower than 6 cm-1, which can be extended to 210-410 nm with an optional second harmonic generator. With a pulse duration shorter than 5ns and an upper repetition rate of 100Hz, the Q-TUNE series provides a perfect coherent light source for precise scientific measurements.
