Ekspla NT370 series High Energy IR Range Tunable Lasers

NT370 series High Energy IR Range Tunable Lasers

The Ekspla NT370 series tunable laser seamlessly integrates in a compact housing the nanosecond optical parametric oscillator and Nd:YAG Q-switched laser.

Pumped by fundamental harmonics output the lasers provides tuning in mid- and far-infrared spectral range. NT373 model delivers eye-safe output at 1570 nm. NT373-XIRx model uses the output from eye‑safe OPO to pump IR crystal based cascade OPO for tunable output in 4400 – 18000 nm range. Customized tuning ranges are available by request. The linewidth of NT373-XIRx model is nearly constant across tuning range and it is less than 6 cm⁻¹. NT377 model produces tunable output in 2500 – 4400 nm range. Pulse energy is exceeding 10 mJ for wavelengths shorter than 3600 nm, while linewidth is below 10 cm⁻¹ for the wavelengths longer than 3000 nm. Read More.

Because of narrow linewidth of output radiation (typically in 6 – 10 cm⁻¹ range) the laser is suitable for many infrared spectroscopic applications, for example cavity ring-down spectroscopy, gas detection and remote sensing.

The device is controlled from the remote keypad or from PC through RS232 interface using LabView™ drivers that are supplied together with the system. The remote pad features a backlit display that is easy to read even while wearing laser safety glasses. System is designed for easy and cost-effective maintenance. Replacement of flashlamps can be done without misalignment of the laser cavity and deterioration of laser performance. OPO pump energy monitoring system helps to increase lifetime of the optical components.
