Pulsed laser system NT230

Q-switchedsolid-stategreen

The NT230 series is a high energy, broadly tunable DPSS laser system designed for advanced laboratory applications. This laser offers hands-free, no-gap tuning from 192 to 2600 nm in a single compact housing, integrating a diode-pumped Q-switched Nd:YAG laser and an optical parametric oscillator (OPO). With a 100 Hz repetition rate, the NT230 series is ideal for laser-induced fluorescence, flash photolysis, photobiology, metrology, and remote sensing. Its innovative diode-pumped design ensures maintenance-free operation and improved stability compared to flash-lamp pumped systems. The system can be controlled remotely via keypad or PC, with a user-friendly interface and backlit display for easy parameter adjustments, even when wearing laser safety eyewear.
