Stabilized HeNe for WS8-series


Stabilized HeNe for WS8-series

The stabilized singlemode HeNe laser (SL03) provides very high frequency stability paired with a short warm-up time. The power supply is built into a seperate case, that allows easy selection of the frequency or amplitudinal stabilization mode.

The delivery includes a 630nm fiber patch cord, a fiber port collimator for easy use and a cage mount for fixation of the laser head.

Optionally the system can be equipped with an optical faraday isolator to minimize optical feedback and increase the stability of the laser system.

Applications, Notes and Downloads

Application Example

Right: Frequency measurement on a stabilized Nd:YAG-laser (532.245 576 nm) by WS Ultimate autocalibrated to a stabilized HeNe-laser (632.991 060 nm, 1 calibration per minute). The absolute accuracy of the measurement is within ± 2 MHz.
 Application Example: Auto-Calibration

Auto-Calibration via Multi-Channel Switch

In order to use this option a calibration laser is fiber coupled to an additional input on the wavelength meter. An switching module will then automatically switch between the laser being monitored and the calibration source. The software then updates the calibration data file. You never need to stop your work or return your wavelength meter to assure its accuracy!
