- High efficiency (2x standard) for high modulation depth
- Visible and IR wavelengths to 2 GHz
- Easy optical alignment

?We are excited to introduce this innovative new line of electro-optic modulators. These new phase modulators incorporate a design to achieve twice the efficiency over our popular standard designs. With the new KTP versions, we've increased the damage thresholds by more than five times that of our LiNbO3 modulators. With low insertion losses, efficient phase modulation and extremely low unwanted amplitude modulation, this new line of phase modulators is ideal for a wide variety of demanding applications. And, using them is easy: simply pass the beam through pre-aligned mechanical apertures for the optimal optical performance. The Model 3363 resonant-modulator drivers can be used to drive these modulators (see )?Resonant-Modulator Drivers.
