The BFS-VRM 03 is one of the worlds fastestanalogue modulated driver for seed applications,DVD-Disk mastering, printing applications, etc.With an output current from zero to 3 A itdelivers enough power to overdrive single modediodes for short pulses.The pulse widths span from 1 ns to cw iscontinuously adressable via the anlaogue inputsignal. This wide span is world unique.Of course there are protective features and thedriver is base plate cooled like all other driversfrom PicoLAS.
