Controller for Diode Lasers
- Versions for 14 pin Modules and Butterfly Packs
- Constant Current or Constant Power Modes
- Modulation Frequencies from DC up to 500MHz
- Temperature Control to ±0.1°C
- Power Stabilisation to ±0.1%
- Facilities for Monitoring Current, Power, Temperature etc
- Optional Control or Monitoring via IEEE-488 Interface
The Driver Module for Lasers or LEDs can be used for any standard 14 pin DIL device with a fibre output.
BNC sockets allow modulation of the laser current in two bands: DC to 50kHz and 10kHz to 500MHz. Both the current and temperature are limited to protect the laser from damage. Internal switches give a wide range of different current limits, temperature ranges and modulation bandwidths. Maximum drive current for a standard unit is 1A (up to 5A by request).
There are three control Modes selected by a front panel switch:
- Constant Current. The value of the current is set by a front panel control
- Direct Current Control via a BNC socket (input range 0-1V).
- Constant Power. Power level set by feedback from internal photo-diode. (No Mode 3 with Butterfly Pack)
Each Power Rack can take up to three Control Modules (or two and an IEEE module)
