Laser diode driver

31 August 2011 Power Electronics / Power Management

The new PCM-7510 module from IXYS is an air-cooled, high power pulsed-current source designed to drive diode lasers, bars and arrays. The touch screen driven system delivers adjustable current pulses from 50 A to 250 A for driving high-power laser diodes and other current dependent applications.

The module provides users with a wide operating envelope with pulse widths variable from 5 microseconds to 5 milliseconds; rise and fall times of 2 microseconds to 8 microseconds; and pulse repetition frequencies variable from 40 Hz to 5000 Hz using the internal trigger, or single shot to 5000 Hz using an external trigger source supporting output power of up to 1250 W.

The PCM-7510 has been designed from the ground up for continuous use in permanent and semi-permanent installations. Examples include driving industrial lasers and extended or long-term scientific and experimental applications. Air cooling eliminates the need for the added support of a liquid cooling system while still maintaining high output power.

The touch screen display and interface provides individual control of each pulser function, while the backlit display provides immediate visual confirmation of all operating parameters, including output current set-point and amplitude, pulse width, repetition frequency, duty cycle, and error and fault messages. The front panel controls allow the user to set parameters such as pulse width, frequency, diode forward voltage etc.

An analog current monitor and a synchronisation output are also provided for monitoring of the current to the laser diode and to synchronise the PCM-7510 with other instruments. In addition to standalone operation, the module can be externally triggered and is equipped with an RS232 interface as standard.
