Description & Options
NT230 series lasers deliver high up to 9 mJ energy pulses at 100 Hz pulse repetition rate, tunable over a broad spectral range. Integrated into a single compact housing, the diode pumped Q-switched Nd:YAG laser and Optical Paramteric Oscillator (OPO) offers hands‑free, no-gap tuning from 193 to 2600 nm. With its 100 Hz repetition rate, the NT230 series laser establishes itself as a versatile tool for many laboratory applications, as laser induced fluorescence, flash photolysis, photobiology, metrology, remote sensing, etc.
Due to the innovative diode‑pumped design, NT230 series lasers features maintenance-free laser operation for an extended period of time and improved stability (compared with flash-lamp pumped counterparts).
NT230 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 system display that is easy to read even with laser safety eyewear.
Due to DPSS pump source, the laser requires little maintenance. It is cooled by a water-air chiller, which further reduces running costs. An OPO pump energy monitor allows monitoring of pump laser performance. A standard feature includes a separate output port for the 355 nm pump beam.

- Due to continuous improvement, all specifi-cations 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.
- Separate –SH and –SF options are available.
- See tuning curves for typical outputs at other wavelengths.
- Measured at 260 nm and 340 nm wavelengths
- FWHM measured with photodiode featuring 1 ns rise time and 300 MHz bandwidth oscilloscope.
- Linewidth is <8 cm⁻¹ for 210 – 405 nm range.
- When wavelength is controlled 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, SF and DUV.
- Full angle measured at the FWHM level at 450 nm.
- 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 harmonic beam is standard. Output ports for other harmonic are optional.
- The pump laser pulse energy will be optimized for best OPO performance and 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.
