4 Modulator Selection Critiera

Operation overview and selection criteria.

5 Amplitude Modulators

The Integrated Optical Amplitude Modulator is a compact

fiber-coupled electro-optical modulator that works based

on MgO:LiNbO3 and LiNbO3 crystals. Providing fast electrooptical

response, it allows amplitude modulation with

frequencies as high as the Gigahertz range.

Available modulators can handle wavelengths in the visible

and the infrared spectral range. Standard-designed modulators

use polarization maintaining single mode fibers to couple

the light in and out. They may also be configured with fiber

systems or connectors of different types. Each modulator

may be fitted with a control & driver unit on special request.

7 Liquid Crystal Spatial Light Modulators

Spatial Light Modulators SLM-S320(d)/640(d) are lineararray

SLMs based on nematic liquid crystals (LC) and are

excellent tools for modulation of ultra fast laser pulses in

the wavelength range 430-1600 nm.

The SLMs are available as single mask configuration for

phase or amplitude/polarization modulation and as dual

mask SLMs for simultaneous modulation of phase and

amplitude in a 4f-arrangement or in a chirped pulse

amplification system.

9 Optical Pulse Picker

The Pulse Picker allows for a reliable reduction of high

pulse laser repetition rates. To achieve this, a fiber-coupled

electro-optical amplitude modulator and control & driver

electronics are combined into a mutually adapted system.

For normal operation, the Pulse Picker requires only the

synchronizing signal of the laser source to be modulated.
