dst11-t193-h2o cooled diode laser system

Diode Laser Systems

Diode lasers from well-known suppliers are integrated with OsTech electronics to turn-key systems or OEM-units.

19″ devices, 3 HU

  • display and keypad
  • input: 110 V – 220 V AC
  • up to 400W optical power
  • water cooled

The product series dst11-t193-h2o combines the features and reliability of OsTech Laser- and TEC controllers with diode laser modules to a turn key laser source. It could be powered by an input voltage of 110~230VAC with power factor correction. Normally the optical power output is located at the back panel. The optical power could be chosen between 100W and 500W. Lasers are water cooled. Multiple laser protection features are incorporated.


As user interface we provide the front panel display, RS232 and an optical isolated analog interface. Cw and pulsed modes are supported. Typical rise time is 25µs, shorter rise times are achievable on request.


It is possible to provide your own laser diode to OsTech. Otherwise we choose the best suited laser for your application.
