EOM Electro-Optic Modulator



Controlling Light by EOM – Electro-Optic Modulator


At a Glance

APEs external Electro-optic Modulator (EOM) is an accessory for laser sources based on APEs long standing experience in designing optoelectronics. It is a dedicated modulator that was designed to be used in Stimulated Raman Scattering (SRS) and other applications that require an amplitude modulated signal. The external EOM can be used with most CW or mode-locked lasers, or synchronously pumped OPOs in the VIS to NIR range (as for example the Levante Emerald or the 1031 nm output of the Emerald Engine). It modulates the amplitude of the beam with a fixed frequency of either 10 MHz or 20 MHz. Modulators for different wavelengths between 420 nm and 1600 nm are available as well.

The EOM combines an electro-optical crystal with a polarizer in a single housing and can be easily mounted onto the optical table. The modulator is connected to the computer through a USB interface and power and phase can be easily remote controlled through the Windows-based Control Software. For easy synchronization the modulator can be connected to the pump laser sync output (typically a signal from a fast photo diode). Alternatively, the frequency can be generated internally.

EOM Package

  • Amplitude modulation for 1064 nm or 1031 nm laser beams
  • Other wavelengths available
  • 10 MHz or 20 MHz fixed modulation frequency (can be phase locked, synchronized to laser frequency: f / 4 or f / 8)
  • Resonant design for reduced RF radiation
  • Ideal tool for SRS imaging applications

EOMs Optimized for the Following Wavelength Ranges

  • 420 … 600 nm
  • 690 … 900 nm
  • 900 … 1200 nm
  • 1030 … 1064 nm
  • 1200 … 1600 nm
