Where to Buy Electro-optic Modulators

Electro-optic crystals like LiNbO₃, LiTaO₃, DKDP, BBO, KTP and RTP crystals in conjunction with HF drivers are available for phase or amplitude modulation. ALPHALAS has a large stock of Pockels cells and phase modulators for most of the standard laser wavelengths.

Raicol Crystals offers electro-optic modulators based on RTP (with a temperature compensating design) or BBO.

Besides, we can supply super-polished LBO crystals which can be used as the center piece of an electro-optic modulator. With its high resistance to laser-induced damage, LBO is very suitable for high-power applications, and its transparency range is large (160 nm – 2600 nm). We offer highly homogeneous crystals with up to 100 × 100 mm² and very low bulk absorption.

With the introduction of the OM6N series of high-speed optical modulators, Thorlabs has designed and manufactured a new all-reflective technology based on deformable mirrors for modulating laser power in the 700 – 1350 nm range. This Pockels cell or AOM alternative introduces nearly zero dispersion to ultrafast laser pulses. This solution extends Thorlabs’ existing collection of adaptive optics and EO modulators.

GWU's portfolio of electro-optical devices can meet even demanding requirements. The BBO or KD^*P Pockels cells offer a high extinction ratio, fast switching capability and a high damage threshold. They can be configured in flexible design, either free-space or fiber-coupled. We also offer driver electronics.

Laserton offers electro-optic Q switches based on KTP Pockels cells with a thermally compensated double crystal design. Our improved hydrothermal-grown KTP crystals overcome the common electrochromism damage problem of flux-grown KTP.

Exail (formerly iXblue) offers the most comprehensive range of commercial electro-optic LiNbO₃ modulators:

• the MXER-LN series of intensity modulators for the C and O bands
• the MPZ-LN phase modulators for the C and O bands
• the near-infrared phase modulators NIR-MPX for the region around 1064 nm
• the NIR-MX Mach–Zehnder modulator for the 1-μm spectral region
• the xx-MPX-LN-0.1 series for wavelengths between 780 nm and 2000 nm and low modulation frequencies
• the MZ-LN family for 1310 nm to 1550 nm with a modulation bandwidth up to 70 GHz
• the space-qualified FM-MX and FM-MPX series
• the PSW-LN and PSC-LN polarization switches and scramblers

In addition, we offer suitable bias controllers, analog and digital drivers. We also have pulse drivers for generating and shaping pulses.

EKSMA Optics produces KTP, KD^*P and BBO Pockels cells for applications like Q-switching of lasers, pulse picking, laser cavity dumping and coupling laser pulses into and from regenerative amplifiers. Our Pockels cells can be supplied with mounting stages, drivers, power supplies and electronics for pulse picking.
