Drivers for high-power continuous wave laser diodes
PicoLAS introduced two new drivers of the LDP-CW 250-40 series to offer efficient control of high-performance continuous wave laser diodes. The electronics are housed in an ultra-compact casing and achieve an output power of 10kW at a power density of 5W/cm³. At an efficiency of 94%, both models generate a maximum output current of 250A and an output voltage of up to 40V.
As usual, PicoLAS replaced the conventional linear current regulators with a self-developed digital alternative that offers significantly higher efficiency. The standard configuration of the driver convinces with an extremely low ripple current of less than 0.85% and, at a maximum modulation frequency of 1kHz, only has an overshoot of less than 3%.
The fast (F) version offers a considerably higher modulation frequency of 50 kHz and a rise time of less than 20µs. Its overshoot also lies below three percent.
All drivers of the LDP-CW 250-40 series have isolated control. They can be fully controlled by analogue signals and are easy to integrate near the laser diode.
LASER COMPONENTS distributes PicoLAS products in Europe and on the North American continent.
