HUDSON, N.H., April 15, 2010 — Laser Components’ LSP40 series plug-and-play driver modules are used to accurately control pulsed laser diodes (PLDs). With just two resistors, the user can regulate both the operating current (and thus the laser power) and the pulse length. All the module requires is an operating voltage of 12 VDC and an external trigger signal.

The laser current can be set to any value up to a maximum of 40 A, and the pulse length can be set to between 30 and 150 ns at 40 A and, at 12 A, from 30 to 1000 ns. With the LSP40 modules, all 905- and 1550-nm pulsed laser diodes available from the company can be operated immediately, and the modules are interchangeable, guaranteeing maximum flexibility.

They allow the user to test different PLDs under varying drive conditions. Packaged in a 40 × 40 × 10-mm shielded housing, the drivers contain the high voltage supply and suitable electronics for switching the PLD drive current to generate short light pulses. Optical peak power is up to 220 W, and maximum repetition rate is 10 kHz.

Applications include medical, rangefinding, laser radar, lidar, burn-in racks, ceilometers and optical triggers. Also available is an evaluation board equipped with two potentiometers for setting the pulse width and drive current. Both the pulse power and the pulse length can be regulated.
