Laser Diode Configurations
The laser diode is connected over the “LASER CONNECTOR” on the
rear panel of the driver. To get the full performance and safety please
only connect a special laser head from Sacher Lasertechnik.
These laser heads incorporate several features.
- Short circuit relay for the laser diode
- Input filter network for current transient protection
- Interlock loop
- bias-T option for high frequency modulation
- separate calibrated photodiode for const power mode (only for high
power TIGER systems)
For maximum flexibility and laser safety the driver supports 4 different
laser diode configurations which are shown in the following schematics.
Configuration 1 (common cathode)
