Resonant Designs with Large Modulation Depths

With patented designs, these modulators achieve high efficiency for high modulation depths. We offer both broadband modulators that can be used at a wide range of frequencies and resonant modulators that operate at a single frequency with much lower drive voltage requirements. The resonant modulators feature a resonant tank circuit to maximize power transfer from driver to crystal, thereby maximizing the voltage across the crystal, lowering required drive voltages by a factor of nearly 10. Each resonant phase modulator is built to the your exact specified frequency.

High Optical Damage Thresholds

Our line of KTP electro-optic modulators offer optical damage thresholds of more than five times that of our LiNbO3 modulators.

Mechanical Apertures for Easy Optical Alignment

The key to obtaining this pure phase modulation is good optical alignment of the beam to the crystal’s propagation axis and accurate orientation of the laser’s electric field with the crystal’s electro-optic axis. New Focus makes proper alignment easy, simply pass the beam through the mechanical apertures.
