Buying Electro-optic Modulators

Your reliable partner for photonics innovations!

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.

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.

Nonlinear crystals pioneers

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.

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.

Hangzhou Shalom EO offers Pockels cells and based on DKDP, BBO, LiNbO₃ and MgO:LiNbO₃ crystals. Shalom EO’s Pockels cells, available in stock and custom versions, deliver the competitive edges of excellent optical transmission at your wavelengths of interest, low half-wave voltage, high damage threshold, and low insertion loss for ideal applications like pulse picking and laser cavity dumping. Various standard and custom extinction ratios are available.

In addition, Shalom EO also provides off-the-shelf and custom electro-optic crystals for EO modulation. The crystals feature rich dimension/orientation options, and large apertures, while also boasting high-precision polishing and different kinds of coatings, Cr–Au electrodes can be deposited. Various substrate materials are available: DKDP, BBO, LiNbO₃, MgO:LiNbO₃, TeO₂, and HGTR-KTP crystals. EO modulation crystals could be offered in the forms of crystal boules, crystal blanks, and crystals with AR coatings and electrodes.

Lasers, Optics, Electronics. Made in Germany.

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.

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.

Change the Color of Light to Expand your Possibilities!

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.
