Q-TUNE-G Series

Q-TUNE-IRThe Q-TUNE-G series is a highly advanced air-cooled, tunable wavelength laser. It offers hands-free, automated tuning from 680 to 2100 nm, delivering up to 12 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-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

Q-TUNE-IR

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.

Q-SHIFT Series

Q-Shift SeriesThe Q-SHIFT series of Q-switched DPSS lasers is designed for researchers and application specialists working in micromachining, dermatology, LIDAR, time-resolved laser spectroscopy, and LIBS applications. With its built-in nonlinear wavelength conversion stage, this series can produce unconventional DPSS wavelengths: 1163, 1177, 1300, 1317, 1551 & 1571 nm. The optional harmonics generator can generate up to the 4th harmonic for each fundamental wavelength, providing even more versatility. This series can produce up to 40mJ/1W @ 1163nm with up to 100Hz repetition rate.
