1. Due to continuous improvements all specifications are subject to change. Unless stated otherwise all specifications are measured at 800 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. Custom build devices with wavelength range of 210 – 4000 nm are available by request. Please inquire for details.
3. Determined by pulse repetition rate of pump source. Q-TUNE-G100 can be configured for 200 Hz rep rate if minimum pump energy requirements are satisfied.
4. When pumped by 40 mJ @1064 nm @100 Hz pulse repetition rate source. See tuning curves for pulse energies at other wavelengths.
5. When pumped by 10 mJ @1064 nm @1 kHz pulse repetition rate source. See tuning curves for pulse energies at other wavelengths.
6. When pumped by 8 W @532 nm @10 kHz pulse repetition rate source. See tuning curves for pulse energies at other wavelengths.
7. When pumped by 30 W @532 nm @100 kHz pulse repetition rate source. See tuning curves for pulse energies at other wavelengths.
8. FWHM level at 800 nm, measured with 350 ps rise time photodiode.
9. Measured during 30 seconds of operation after warm-up.
10. 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.
11. Beam diameter is measured 20 cm from laser output at the 4σ level.
12. Full angle measured at the 4σ level.
13. Laser can be powered from appropriate 12 or 28 VDC power source, depending on model. Please inquire for details.
Description
Q-TUNE-HR is an Optical Parametric Oscillator (OPO) producing tunable wavelength in 750-1800 nm range with up to 100 kHz pulse repetition rate.
Up to 100 kHz pulse repetition rate make Q-TUNE-HR perfect coherent light source for micromaching, Raman spectroscopy, microscopy, remote sensing applications.
Q-TUNE-HR needs external pump source with > 350 µJ pulse energy, 5-7 ns FWHM pulse duration @ 532 nm. Pulse repetition rate can be in 10-100 kHz range, while pump power – in 3.5-30 W range. Contact us for more details about recommended pump sources.
By default OPO is optimized to produce maximum output in 1200-1800 nm range. As option, unit can be optimized for 750-950 nm range.
All laser electronics are integrated into housing of the Q-TUNE and the only external module is mains adapter that provides 12 VDC, 20-50 W power (depending on model).
OPO is 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 bypass port for access to pump laser beam.
