Pulsed laser system NT270

nanosecondQ-switchedsolid-state

The NT270 series is a tunable wavelength NIR-MIR range DPSS laser system designed for advanced IR applications. It delivers hands-free, no-gap tuning from 2500 nm to 4475 nm at a 1 kHz repetition rate, all from a single compact housing. This wide IR tuning range makes it an excellent choice for applications such as scanning Near-field Optical Microscopy (s-SNOM), single molecule vibrational spectroscopy, and gas spectroscopy.

Description
NT270 series tunable laser systems integrate a nanosecond Optical Parametric Oscillator (OPO) and Diode-Pumped Solid–State (DPSS) Q-switched pump laser into a single compact housing. Diode pumping enables fast data acquisition at high pulse repetition rates up to 1 kHz while avoiding frequent flashlamp changes. The pump lasers do not require water for cooling, reducing running and maintenance costs. All lasers feature motorized tuning across the specified range, with output wavelength settable from a control pad with a backlit display or from a PC using supplied LabVIEW™ drivers. High conversion efficiency, stable output, easy maintenance, and compact size make these systems an excellent choice for many applications.
