External Cavity Diode Laser
ECD-003

 

The MOGLabs external cavity diode laser offers research quality at a teaching-lab price. Model ECD-003 is robust, stable, and insensitive to external vibrations. The performance is excellent when used with a MOGLabs Diode Laser Controller, with modehop- free scanning range of more than 10 GHz and linewidth below 100 kHz using a low-cost uncoated 780 nm consumer diode. Diode replacement and realignment are easily accomplished by the end-user.

Features
  • Wide mode-hop free scan range
  • Narrow linewidth
  • Fast piezo feedback
  • Precision alignment controls
  • Microwave RF modulation input
  • Diode protection circuit and relay
Benefits
  • High-performance, low cost
  • Stable, robust
  • Low frequency noise
  • High feedback bandwidth
  • Use with MOGLabs external cavity diode laser controller, or your existing commercial or homemade electronics
Applications
  • Laser cooling and trapping
  • Bose-Einstein condensation
  • Quantum optics: squeezed light
  • Electromagnetic transparency and slow light
  • Time and frequency standards
  • Laser spectroscopy
  • Physics teaching labs
