Laser Diode Fiber Light Source

Ordering Code:
  • Each channel has a BNC input connector for up to 10 kHz TTL/analog modulation of the driving current and a BNC output connector for monitoring the driving current or for synchronization with other devices. Its laser safety features include a rear panel interlock connector, a master key switch and a white LED illuminated control knobs indicating laser diode operation. Also, each FC optical connector has a metal dust cap that acts as protective mechanical shutter. Unlike most commercial laser diode drivers, our linear driving electronics eliminates leakage current to get no light output for zero set current. That means no residual light exits from the laser diode when the driving current is set to zero. This feature is important for optogenetics experiments. The available wavelengths and fiber-coupled power values are given in the table below. For multichannel models, any wavelength combination is available.

    Doric light sources can be controlled using the Doric Neuroscience Studio, allowing more complex forms of light source control than through standalone use.  For example, it is possible to program simple or complex light pulse train sequences and to control their start with an external trigger signal in multiple different ways, see the trigger presentation video.

    If your application requires control of the device with another software, we can provide the API to control from Matlab, Python, or C++, please contact our technical support for more details.
