Pulsed laser system NT260

tunablehigh-powerfor spectroscopy

The NT260 series is a narrow linewidth 10 kHz tunable laser system designed for scientific applications requiring high spectral brightness and precision. It delivers hands-free, no gap tuning from 192 to 2600 nm at a 10 kHz rate from a single box, with up to 0.7 W output power and linewidths less than 3 cm⁻¹. This makes it ideal for demanding applications such as calibration of detectors and spectroradiometers, metrology, and gas spectroscopy. The system features pioneering patented Q-switched/mode-locked operation technology, integrated monitoring, fast wavelength scan, and a rugged monolithic frame for reliability and ease of transport. Flexible control is available via keypad or PC, and the system offers a two-year warranty.

Description
NT262, a member of the NT260 series, is a unique narrow linewidth 10 kHz OPO. Its patented technology enables up to 0.7 W output in the 192–2600 nm range while maintaining <3 cm⁻¹ (typically <2 cm⁻¹ at most wavelengths) linewidth, highly beneficial for applications requiring narrow linewidth and high spectral brightness. The system is suitable for high-resolution applications such as calibration, metrology, and gas spectroscopy, as well as fluorescence and pump-probe experiments. High repetition rate and hands-free tuning facilitate fast and easy data collection. The system is highly stable, with excellent short and long-term energy and power stability, and a smaller M² value compared to traditional OPO systems. It is reliable due to a low generation threshold and easy operation, housed in a rugged, monolithic frame for high reliability and low maintenance.
