Description & Options
NT242 series lasers produce pulses at an unprecedented 1 kHz pulse repetition rate, tunable over a broad spectral range. Integrated into a single compact housing, the diode pumped Q-switched Nd:YAG laser and OPO offers hands‑free, no-gap tuning from 210 to 2600 nm. With its 1000 Hz repetition rate, the NT242 series laser establishes itself as a versatile tool for many laboratory applications, including laser induced fluorescence, flash photolysis, photobiology, metrology, remote sensing, etc.
NT242 series systems can be controlled from a remote control pad or/and a computer using supplied LabVIEW™ drivers. The control pad allows easy control of all parameters and features on a backlit display that is easy to read even with laser safety eyewear.
Thanks to a DPSS pump source, the laser requires little maintenance. It is cooled by a built-in chiller, which further reduces running costs. A built‑in OPO pump energy monitor allows monitoring of pump laser performance without the use of external power meters. The optional feature provides a separate output port for the 1064, 532 or 355 nm beam.

- Due to continuous improvement, all specifications are subject to change. Parameters marked typical are illustrative; they are indications of typical performance and will vary with each unit we manufacture. Unless stated otherwise, all specifications are measured at 450 nm and for basic system without options.
- See tuning curves for typical outputs at other wavelengths.
- Measured at FWHM level with photodiode featuring 1 ns rise time and 300 MHz bandwidth oscilloscope.
- Linewidth is <8 cm⁻¹ for 210 – 405 nm range.
- For manual input from PC. When wavelength is controlled from keypad, tuning resolution is 0.1 nm for signal, 1 nm for idler and 0.05 nm for SH and SF.
- Beam diameter is measured at 450 nm at the 1/e2 level and can vary depending on the pump pulse energy.
- Separate output port for the 3rd and other harmonic are optional.
- The laser max pulse energy will be optimized for best OPO performance. The actual pump laser output can vary with each unit we manufacture.
Note: Laser must be connected to the mains electricity all the time. If there will be no mains electricity for longer that 1 hour then laser (system) needs warm up for a few hours before switching on.
