10 kW Output Power with Small Footprint and Highly Efficient Design

US43-071

For high power laser diode applications, PicoLAS has released two new versions of its continuous wave (CW) laser diode driver series, LDP-CW 250-40. The drivers achieve 10 kW output power in an exceptionally compact enclosure, with power density of 5 W/cm³. Both models of the laser controller generate maximum output current of up to 250 A and compliance voltage of up to 40 V with efficiency up to 94%.

PicoLAS integrates an innovative digital current regulator in all its designs resulting in considerably less losses compared to commonly used linear regulators. In the standard configuration, the LDP-CW 250-40 features a very low current ripple of <0.8 %, minimal overshoot of <3 % with a maximum modulation frequency of 1 kHz.

The fast modulated (F) version increases the maximum modulation frequency up to 50 kHz (-3 dB) with a current rise time of <20 µs, while keeping the maximum overshoot below 3 %.
The LDP-CW 250-40 has an isolated control interface and can be completely controlled by analog signals and easily integrated close to the laser diode.
