These modules are used to control the current of laser diodes, used in a range of applications requiring drive currents of up to 1A. Applications include Fiber Laser, Direct Drive Laser Diodes, DPSS and EDFA.

​These modules feature all the required drive circuitry for constant-current operation, along with over-current and over-temperature protection circuitry. The modules come in a small form factor package (20mm X 27.5mm X 6mm), and uniquely to ModularOne; versions are available to allow for grounded-case operation for all available laser diode ​assemblies. (Refer to "Laser Diode Configurations" document for further details). They feature an integrated Voltage Reference; Temperature Sensor and are specifed over the industrial temperature range.

For even faster implementation the modules are also available pre-soldered to a printed circuit board, together with most other components needed to implement a basic system. Simply connect a power supply and your laser / assembly of choice - See Laser Driver Board
