NT235 series lasers produce high up to 10 mJ energy pulses at 100 Hz pulse repetition rate, tunable over a broad spectral range. Integrated into a single compact and robust housing, the diode pumped only Q-switched Nd:YAG laser and OPO offers hands‑free, tuning from 335 to 2600 nm. With its 100 Hz repetition rate, the NT235 series laser establishes itself as a versatile tool for many laboratory applications, including photo acoustic imaging, laser induced fluorescence, flash photolysis, photobiology, metrology.

Diode-pumped design, gives maintenance-free laser operation for an extended period of time and improved stability (compared with flash-lamp pumped counterparts).It is cooled by a build-in chiller, which further reduces running costs. OPO pump energy monitor allows monitoring of pump laser performance without the use of external power meters. NT235 series systems controlled from a user-friendly remote control pad or/and a computer. 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.

Accessories and optional items

  • Optional items and accessories allows the laser to be configured for any application:
  • Tuning range extension in UV range (335 – 531 nm) by second harmonics generation
  • Fiber coupled output in 350 – 2300 nm range (please inquire for precise fiber coupler selection)
  • Attenuator option for 670 – 2600 nm range.

1) Due to continuous improvements all specifications are subject to change. 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 800 nm.

2) Tuning range of 335 – 532 nm is provided by SH 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) Full angle measured at FWHM level 800 nm.

7) Beam diameter is measured at 800 nm at the FWHM level and can vary depending on the pump pulse energy.

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