Q-Tune-IR Series - Tunable, Diode-Pumped Nanosecond Lasers Optimized for MIR

The newly developed Q-Tune-IR is tunable in the infrared wavelength range from 1380 to 4500 nm. Typical pulse energy is >20mJ@1500nm and >6.5mJ@3500nm at 3-4 pulse duration, <10cm-1 line width and 10Hz or 20Hz repetition rate depending on model. A cost-effective version with lower pulse energy is also available. Q-Tune-IR can be used as light source in many spectroscopic applications like infrared spetrophotometry, cavity ring-down spectroscopy, gas spectroscopy, single molecule vibrational spectroscopy and scanning near-field optical microscopy.

Q-TUNE-IR is high peak power coherent light source for infrared spectroscopy, infrared spectrophotometry, metrology, single molecule vibrational microscopy, remote sensing.
Q-TUNE-IR employs Optical Parametric Oscillator (OPO) to produce tunable wavelength in 1380-4500 nm range with linewidth of less than 10 cm-1. Broadband version with linewidth up to 200 cm-1 is available by request.
The heart of any laser system is master oscillator. QLI breakthrough water-free laser crystal pumping technology allows to produce high quality laser beam with up to 120 mJ pulse energy at 1053 or 1064 nm. Less than 7 ns pulse duration produced by pump laser is one more advantage, facilitating operation of OPO, which requires high peak power pulses for reliable operation.
Advanced laser design resulted in compact, user-friendly turnkey system that requires little maintenance. There is no chillers or bulky power supplies that one needs fit under the table. All laser electronics is integrated into housing of the Q-TUNE-IR and the only external module is mains adapter that provides 12 or 28 VDC, 50-150 W power (depending on model).
Q-TUNE-IR can be configured with different our pump lasers for optimal match to your application. If high pulse energy is required, Q-TUNE-IR can be configured for 6.5 mJ output @ 3500 nm at 10 Hz pulse repetition rate. Cost effective solution is also available, Q-TUNE-IR-C10 can be configured for 10 Hz operation with 2 mJ @ 3500 nm pulse energy.
Both pump laser and OPO are controlled trough single Ethernet port via build-in web-server. There is no need to install control software any computer or even cell phone with modern web-browser will be able to control Q-TUNE-IR. API is also provided for integration with user devices.
In addition to tunable wavelength output, the Q-TUNE-IR provides a extra port for access to the pump laser beam.

Optional extensions available by request:

  • Compact spectrometer for monitoring of OPO wavelength and linewidth.
  • Build-in broadband attenuator for pulse energy control
  • Dispersive wavelength selector for spectrally pure output
