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-G Series

sleek, modern, light grey colored OPO & DPSS laser housing

The Q-TUNE-G series is a highly advanced air-cooled, tunable wavelength laser. It offers hands-free, automated tuning from 680 to 2300 nm, delivering up to 11 mJ pulse energy in the near-IR range. With a <10 cm-¹ linewidth and up to 100 Hz pulse repetition rate, it’s ideal for photoacoustic imaging, non-linear spectroscopy, and more. The user-friendly GUI and microprocessor control ensure ease of use, while the water-free, air-cooled design optimizes performance. The Q-TUNE-G series sets a new standard in precision and efficiency for researchers across disciplines.

Q-TUNE-HR Series

sleek, modern, light grey colored OPO & DPSS laser housingThe Q-TUNE-HR series is a high repetition rate OPO producing a tunable wavelength range from ≈ 750 – 1800 nm and up to 100 kHz pulse repetition rate, the perfect coherent light source for micromachining, Raman spectroscopy, microscopy, and remote sensing applications. Q-TUNE-HR requires an external pump source with > 350 μJ pulse energy and 5 – 7 ns FWHM pulse duration @ 532 nm for operation: pulse repetition rate can be in 10 – 100 kHz range and acceptable pump power in the 3.5 – 30 W range. By default OPO is optimized to produce maximum output in 1200 – 1800 nm range (optional: 750 – 950 nm). In addition to the tunable range, the pump laser wavelength is accessible through a convenient bypass port.

Q-TUNE-IR Series

Q-TUNE-IRThe Q-TUNE-IR series is the perfect high peak power, coherent DPSS light source for researchers with infrared spectroscopy applications. This series uses an Optical Parametric Oscillator (OPO) to produce a tunable wavelength of 1380–4500nm (<10 cm-1 linewidth), achieving > 15mJ of pulse energy at the peak of the tuning curve. 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 while providing a guaranteed > 2 G shot pump diode lifetime.

Q-TUNE Series


The Q-TUNE series is a highly efficient, air-cooled, tunable wavelength laser, providing up to 8mJ, shorter than 5ns pulses at up to 100Hz, designed for 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 extend to 210-410 nm with an optional second harmonic generator. Options for air purging for UV optics, spectrometer, and fiber-coupled OPO output are also available.

TLS Series

Users can tune output power, wavelengths from 410-1700nm by choosing the VIS, IR, SWIR, or a custom configuration, and real-time bandwidth control for TLS-Red (10 or 20nm fixed for TLS-Blue). These picosecond tunable lasers are suitable for various fields that require precision scanning and high output from fluorescence microscopy to time-resolved spectroscopy, such as TCSPC, Hyperspectral imaging, Machine vision, Semiconductors, Sensors, and other applications.
