Area of Science:

  • Engineering
  • Laboratory Safety
  • Optics and Photonics

Background:

  • University research laboratories often utilize multiple high-powered lasers.
  • Limited financial resources can restrict the implementation of advanced safety and monitoring systems.
  • Existing laser monitoring solutions may be costly or require extensive infrastructure.

Purpose of the Study:

  • To design and build an open-source remote monitoring system for laser operation.
  • To provide a cost-effective and easily deployable solution for university research laboratories.
  • To enhance laboratory safety by visually indicating laser usage.

Main Methods:

  • Developed a 3D-printed remote monitoring system.
  • The system selectively monitors laser current or TTL shutter signals.
  • Implemented wireless communication to indicate laser activity at laboratory entrances.

Main Results:

  • The system successfully provides illuminated visual indication of laser operation.
  • Multiple lasers can be monitored within a single room.
  • Wireless functionality eliminates the need for expensive in-wall wiring.
  • An optional emergency shut-off switch was incorporated.

Conclusions:

  • The open-source laser monitoring system is a readily deployable and cost-effective solution for research laboratories.
  • The wireless, 3D-printed design addresses the financial and infrastructural limitations of traditional monitoring systems.
  • The system enhances safety by providing clear visual cues of laser activity, with an optional emergency shut-off feature for added security.
