AeroDIODE has developed the fiber modulator – a high-speed intensity modulator and optical switch based on a semiconductor optical amplifier (SOA). It is available over a wide wavelength range from 750 to 1650 nm. Key features are high speed (down to 1 ns rise/fall time), high dynamic range (>48 dB), high extinction ratio (>50 dB) and an easy to use graphical user interface with multiple software libraries (LabVIEW, Python etc.). AeroDIODE also offers the Semiconductor Optical Amplifier alone or the SOA driver in either CW or pulsed configuration.

AeroDIODE also offers a wide range of fiber coupled AOMs (Acousto Optic Modulators) with various types of digital (TTL) or analog RF drivers.

With the introduction of the OM6N series of high-speed optical modulators, Thorlabs has designed and developed 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.

Hangzhou Shalom EO offers off-the-shelf and custom Pockels cells, we can provide off-the-shelf and customized BBO, DKDP, LiNbO₃ and MgO:LiNbO₃ Pockels cells for electro-optical modulation.

• The DKDP Pockels cells are of the longitudinal type. They feature high deuteration (>98%), fast rise time, and a maximum aperture of 50 mm.
• The BBO Pockels cells are the best choice for high reptition rate Q-switching, with the additional advantages of high damage threshold and low insertion loss.
• The LiNbO₃ and MgO:LiNbO₃ Pockels cells are of the transverse type. They have large electro-optic coefficients, good transmission up to 4.0 µm, and low half wave voltage. Aperture sizes of 2.5 mm to 9 mm are available.

In addition, we also provide RTP Q-switches, and electro-optical and acoustic-optical crystals (BBO, DKDP, LiNbO₃ / MgO:LiNbO₃, TeO₂) which are the core elements used in optical modulators and Pockels cells.

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.

Lasers, Optics, Electronics. Made in Germany.

Phase and amplitude electro-optical as well as acousto-optical modulators in a standard and customer-specific configuration, including the drivers are available on order from ALPHALAS. Standard wavelengths are 1030 nm and 1064 nm, but customized wavelengths can also be supplied.
