Features

  • Tailored for laser cooling & trapping of Eu isotopes:
  • => tailored modulation frequency range
  • => matched BBAR coating / optical power
  • => optimised modulation efficiency / high Q-factors
  • Thoroughly tried and tested
  • Precision frequency adjustment included
  • Standard large aperture (3x3mm) for easy alignment
  • Mounting options for s- and p-polarised light

Typical Applications

  • Laser cooling / Repumper generation
  • Quantum state manipulation (Raman transitions,...)
  • Laser frequency stabilisation (PDH, FM/MTS)
