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 195 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 user-friendly 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 stand alone 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. A standard feature includes a separate output port for the 355 nm pump beam.

 1) Due to continuous improvement, all specifications are subject to change without notice. For latest product information please visit EKSPLA. Parameters marked typical are not specifications. They are indications of typical performance and will vary with each unit we manufacture. Unless stated otherwise, all specifications are measured at 450 nm.

2) Tuning range of 210 – 405 nm is provided by SH/SFG option.

3) See tuning curves for typical outputs at other wavelengths.

4) Inquire for other pulse repetition rates.

5) FWHM measured with photodiode featuring 1 ns rise time and 300 MHz bandwidth oscilloscope.

6) Linewidth is <8 cm-1 for 210- 405 nm range and 10cm-1 for 195-209 nm

7) Beam diameter is measured at 450 nm at the 1/e2 level and can vary depending on the pump pulse energy.

8) Separate output port for the 3rd harmonics beam is standard. Output ports for other harmonics are optional.

9) The laser max pulse energy will be optimized for best OPO performance. The actual pump laser output can vary with each unit we manufacture.
