Description
Q-TUNE is using Optical Parametric Oscillator (OPO) to produce tunable wavelength in 410-2300 nm range with linewidth narrower that 6 cm-1. Optional second harmonic generator extends tuning range to 210-410 nm with linewidth narrower that 12 cm-1. Combined with shorter than 5 ns pulse duration and up to 100 Hz pulse repetition rate Q-TUNE is perfect coherent light source for temporally resolved spectroscopy, metrology, photoacoustic imaging.
QLI breakthrough water-free laser crystal pumping technology allows to produce high quality laser beam with up to 100 mJ pulse energy. Advanced laser design resulted in very compact, user-friendly turnkey system that requires little maintenance. There are no chillers or bulky power supplies that one needs to fit under the table. All laser electronics are integrated into housing of the Q-TUNE and the only external module is mains adapter that provides 12 or 28 VDC, 50-150 W power (depending on model).
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. API is also provided for integration with user devices.
In addition to tunable wavelength output, the Q-TUNE provides two extra ports for access to pump laser beams.
Optional extensions available by request:
- Compact spectrometer for monitoring of OPO wavelength and linewidth.
- Motorized attenuator for VIS or NIR range.
- Broadband OPO pulse energy monitor.
- Fiber coupled OPO output.
Applications
- Temporally resolved laser spectroscopy (for example, Light Induced Fluorescence Spectroscopy (LIFS)).
- Non-linear laser spectroscopy.
- Confocal microscopy.
- Metrology.
- Photo-acoustics imaging.

1. Due to continuous improvements all specifications are subject to change. Unless stated otherwise all specifications are measured at 450 nm and max pulse repetition rate. The parameters marked typical are not specifications. They are indications of typical performance and will vary with each unit we manufacture.
2. Optional extension down to 210 nm is available with second harmonic generator.
3. Factory-set pulse repetition rate in internal triggering mode. Pulse repetition rate can be divided-down to 1 Hz.
4. Measured at 450 nm output. See tuning curves for pulse energies at other wavelengths.
5. FWHM level at 1064 or 1053 nm, measured with 350 ps rise time photodiode.
6. Measured during 30 seconds operation after warm-up.
7. Over 8 hour period after 20 minutes of warm-up, when ambient temperature variation is less than ±2 °C. Power value is calculated every 1 second.
8. Beam diameter is measured 20 cm from laser output at the 4σ level.
9. Full angle measured at the 4σ level.
10. In respect to falling edge of pump diode triggering pulse.
11. Laser pulse energy is optimized for OPO pumping and may differ from stand-alone laser specifications.
12. Outputs can be configured for simultaneous or non-simultaneous with OPO operation. Values indicated here are for non-simultaneous operation.
13. Power adapter is integrated with air purging unit.
14. Laser can be powered from appropriate 12 or 28 VDC power source, depending on model. Please inquire for details.
