1380-4500 nm波长可调谐红外调Q激光器——Q-TUNE-IR

Q-TUNE-IR is a 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.
There two types of OPO coatings available. The first one is optimized for maximum transmission in 2.1 µm range (option -TC1). The second one is optimized for maximum transmission in 3.3 – 3.9 µm range (option -TC2). See tuning curves in datasheet for comparison.
QLI breakthrough water-free laser crystal pumping technology allows to produce high quality laser beam with up to 100 mJ pulse energy. There are no chillers or bulky power supplies that one needs fit under the table. All laser electronics are 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 dedicated QLI pump laser for optimal match to your application. If high pulse energy is required, Q-TUNE-IR can be configured for 6 mJ output @ 3300 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 @ 3300 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 OPO wavelength and linewidth monitoring.
• Build-in broadband attenuator for pulse energy control.
• Air purging for removal of water vapor absorption lines and improved lifetime of optics.

参数 ¹⁾

1. Due to continuous improvements all specifications are subject to change. Unless stated otherwise all specifications are measured at 3300 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. There are two wavelengths at the exit port in 1800 – 2500 nm range corresponding to signal and idler of OPO. Configurations for single wavelength output and/or no gap in 2800-2900 nm range are available. Please inquire for details.
3. Factory-set pulse repetition rate in internal triggering mode. Pulse repetition rate can be divided-down to 1 Hz.
