Perfect for measuring CH3i in the nuclear industry, this UniMir 11.3µm (885 cm-1) model is a single-mode DFB QCL, operating in CW mode with 10mW output power (with the base plate of the HHL-package at 20oC). The full tunable range is >3cm-1, while the continuous tuning range, free from ‘mode hopping’ is >1cm-1.
The uniMir Series is a long-wavelength, single-frequency, DFB, CW Quantum Cascade Laser based on proprietary technology. The technology’s versatility allows them to address any wavelength between 10 and 18µm in CW and up to 21µm in pulsed mode. Now commercially available in a sealed High Heat Load (HHL) package, with integrated collimating lens, thermistor, and thermoelectric cooler (TEC), well suited for integration into systems, or as a stand-alone turnkey system for R&D and detection applications.
Benefits:
- Gas Sensing Benefits:
- Very tight linewidth that drives the very high sensitivity of gas sensing
- Low power consumption for integration in portable gas analyzers
- Very stable over time with good Allan deviation results when integrated inside a gas analyzer
- Operation Benefits:
- CW operation delivering mW levels of output power at room temperature
- Pulsed operation for larger tuning range is a good option because at these long wavelengths, the intrapulse linewidth broadening is relatively small
- Single-mode, mode-hop-free tunability – Controlling operating temperature with TEC enables wavelength tuning without mode hopping while keeping a single-mode operation
The uniMir series is well suited for integration into systems, or as a stand-alone turnkey system for R&D and detection applications. The technology’s versatility allows them to address any wavelength between 10 and 18µm in CW and up to 21µm in pulsed mode, opening the way for high-resolution spectroscopy applications in this spectral range, notably for the detection of BTEX, but also CH3I, HCN and many other compounds. With very tight linewidths, the uniMir series provides high sensitivity for gas detection, while low power consumption ensures long battery life in portable analyzers.
The uniMir lasers are mounted on a thermoelectric cooler (TEC) inside a sealed High Heat Load (HHL) package, integrating a collimation lens and a thermistor to readout the laser chip temperature. By controlling the chip’s operating temperature through the TEC element inside the laser’s package, customers can tune the emission wavelength without mode hopping while keeping a single-mode operation. The lasers operate in both continuous-wave (CW) and pulsed modes, with the latter providing a larger tuning range and minimal intrapulse linewidth broadening at these long wavelengths.
These benefits make the uniMir laser family an excellent choice for gas analysis in challenging environments, offering mW levels of output power and stable performance over time, with good Allan deviation results when integrated inside a gas analyzer.
