High frequency laser diode driver

A new high power laser diode driver has been developed and tested. The possibilities for driving high power laser diode bars and stacks at high frequencies has been shown. frequency of 10kHz Isolated input – galvanic isolation of 1kV between the input signal and driver Adjustable laser current – in form of a potentiometer, to be able to set maximum laser current Laser current rising slowly – to avoid overshoots Laser diode forward voltage drop up to 5V – needed to design proper. Maxim’s Gbps telecommunication laser drivers such as the MAX and the MAX II. Laser Diode Characteristics In general, coherent optical output can only be generated and maintained in a semiconductor laser diode when the laser current is above its threshold value. For fast switching operation, it is a common.

The single channel A, , V 5 kHz high-power laser diode driver. High current laser diode driver dedicated for 20 W, 40 W, 60 W, and other similar power laser diodes. Independent supply inputs help to get rid of noise in the logic level part of the driver while laser. The Current Limit can be set below the laser diode maximum current, and used as a tool to minimize the Internal Power Dissipation of the laser diode driver. Load: For a laser diode driver, the load consists of the laser diode and / or the photodiode. IMON: This is an analog voltage proportional to the laser diode current. Transfer functions are provided in individual driver datasheets. AMI’s high current high power driver the Model A is an OEM design for high power DPSS laser and illumination applications. AMI’s high speed high peak power Model is ideal for driving pin butterfly packaged laser diode modules for use in pulsed fiber MOPA systems for materials processing, LIDAR systems for remote sensing, laser communication applications and rangefinding.
