Laser Diode by Mir Sense

Note: Your Quotation Request will be directed to Mir Sense.

The uniMir from Mir Sense is a Quantum Cascade Laser Diode that has a wavelength range of 10 µm - 17 µm. It delivers an output power of 5 mW - 10 mW (below 15 µm), 1 mW - 5 mW (above 15 µm), and up to 20 mW (with fabry-perot laser). This single-mode Distributed Feedback laser diode operates in both pulsed mode (QCW) and continuous wave mode (CW). It has a line width of less than 100 MHz (free-running with suitable electronics for CW) and full accessible wavelength range of 3 cm-1

The uniMir produces a beam of diameter 4 mm and has a beam divergence of up to 10 mrad. It has TEM00 mode with a continuous tuning range of 1 cm-1 and side mode suppression ratio (SMSR) above 25 dB. This linear vertically polarized laser diode has a built-in temperature sensor thermistor with a resistance of 10 kOhms. It is available in a High-Heat Load (HHL) package and is ideal for spectroscopy applications.
