DESCRIPTION
The Electro-Optic Modulator is available as standard at 10 MHz, with other frequencies possible on request. It's the perfect solution for researchers wishing to stabilise single-frequency lasers by modulating a probe beam in a Frequency Modulation spectroscopy (FM Spectroscopy) set-up, while leaving the main beam unaffected. The EOM can be mounted in a standard 1 inch mirror mount.
For ease of purchase we can supply a suitable oscillator, the TTi TG120, for its low cost, functionality and reliability in order to have a fully functional system delivered to your bench.
APPLICATIONS
Generation of side-bands on single-frequency lasers for high resolution locking techniques, such as frequency modulation saturation spectroscopy or stabilization to an optical resonator.
