The LDP-AV 4N55-90 is able to drive four laser diodes with a fixed pulse duration of 5.5ns with up to 90A each. whereas the 16 channel LDP-AV 16N45-40 offers up to 40A drive per laser diode in 5.5ns.
Direct mounting of the laser diodes on top of the driver board enables a high power density from a compact footprint. Customisation of these driver boards is also possible, for example laser diode pad position or pulse duration.
