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 Series

Q-TUNE-IR

The Q-TUNE series is a high energy, compact, tunable wavelength laser consisting of an Optical Parametric Oscillator (OPO) capable of producing a tunable wavelength range of 410-2300 nm with a linewidth narrower than 6 cm-1. Optional second harmonic generator extends the tuning range to 210-410 nm.
The combination of a pulse duration shorter than 5ns and an upper repetition rate of 100Hz, makes the Q-TUNE a perfect coherent light source for temporally resolved spectroscopy, metrology, photo-acoustic imaging and remote sensing applications.

Q-TUNE-IR Series

Q-TUNE-IR 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.
