Benchtop laser driver / laser controller DYNALASE-ULC

Fast diode laser driver and laser controller for laboratory set-ups

Features

·         Easy operation of different lsaer diodes

·          Very fast, analog modulation capability  (100 MHz (-3dB))

·          High output current (up to 3.0 A)

·         Precise control of the laser diode temperature 

·         Easy integration into optical set-ups due to compatibility with standard breadboard mountings (rods, posts, etc.)

Set-up of the laser driver system

·         Universal controller for all driver versions

·         TO driver version for mounting laser diodes in TO packge (9 mm, 5.6 mm und 3.8 mm in diameter)

·         BF driver version for mounting laser diodes in 14 pin butterfly package

·         Analog output stage allows generation of arbitrary waveforms such as sine waves, puls pattern, chirp signals, etc.

·         Monitoring and parameterization of the system can be done from a PC via remote control

Functions of the controller unit

·         User-Interface for monitoring and changing system parameters

·         Offset adjustement to add a bias to the applied modulation signal

·         Limit adjustment for the maximum output current of the driver (independent of applied modulation signal)

·         Detection of the connected driver version

·         Temperature control loop processing

·         Power supply

Functions of the laser driver unit

·         Laser diode mount (TO or Butterfly)

·         High performance pump current source (the actual laser driver)

·         Safety funtions to avoid damage to the laser diodes

·         Active and passive temperature control componentes (TEC, thermistor, heat sink)

Supported laser diodes

The TO versions of the DYNALASE driver units can be equipped with all common laser diodes in TO packages with 5.6 mm and 9 mm in diameter. Also we offer a version with a different mount for 3.8 mm packages.

The drivers can not only be used with red and infra-red diodes, but also with UV and blue diodes with forward voltages up to 7.5 V.

Examples:

·         ML520G72 - Mitsubishi - 500 mW - 638 nm - TO 5.6 mm

·         PL T4 NSB - Osram OS - 50 mW - 450 nm - TO 38 Icut
