This low-cost EOM is available at frequencies from 5 to 20 MHz (standard models listed below), with other frequencies possible on request. It is the perfect solution for researchers wishing to stabilise single-frequency lasers by modulating a probe beam in a Frequency Modulation spectroscopy set-up, while leaving the main beam unaffected. The EOM can be mounted in a standard 1”mirror mount, allowing for simple placement and alignment within your optical setup.
The unit may be supplied with a suitable optional low-voltage oscillator. Coatings for different wavelength ranges are available.
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.
