This system performs high-quality measurements across a wavelength range from 2 µm to 11 µm. Like all other wavelength meters in the HighFinesse/Angstrom series, the WS-200 IR3 performs wavelength measurements with maximum precision (200 MHz) and high speed. CW and pulsed lasers with narrowband emission can be examined, monitored, and controlled, even actively.

 

Based on a robust Fizeau interferometer configuration with no moving parts, this wavelength meter delivers maximum performance even under challenging conditions. The highly sensitive detector enables high-speed data processing algorithms and allows for single-pulse measurements at repetition rates up to 150 Hz. A fiber optic input port for laser radiation coupling ensures convenient operation. The device is computer-controlled via a USB 2.0 interface.

Fully automated long-term measurements can be recorded and the data converted into different formats for further evaluation, for example, assessing the long-term frequency stability of a laser system.

Multiple options are available, such as PID control, TTL synchronization, and beamwidth measurement.
