WS8 Wavemeter to M Squared SolsTiS Laser Feedback

Bryce M. Henson, Jacob A. Ross
Status: This Code is working but messy inside. Unit Testing is not implemented.

Build Status

Uses software in the loop feedback of the optical frequency of a M Squared SolsTiS Laser (with doubler) to a WS8 wavemeter. Checks if the laser has unlocked either the doubler or the Ti:Saf and relocks. Can instigate an unlock of the doubler and a scan of the etalon. Provides a detailed log file in JSON format.

Feedback Demonstration
Figure 1- The program is able to perform low bandwith (~20Hz) feedback to the laser freqeuncy with excelent stability and range.

To Do

  • Nice picture
  • Documentation
  • move much of the code into functions
  • move pid into separate project
    • build tests for pid
  • clean up unused functions

Contributions

This project would not have been possible without the many open source tools that it is based on.
