  • Page 11: Introduction

    Modules derived from the VisUV/IR laser platform can be used as stand-alone devices including an internal driver unit with all common driving functions as found in the Sepia PDL 828 from PicoQuant. The modules can be operated at 12 different internally selectable repetition rates ranging from 80 MHz to 31.25 kHz and can also be triggered externally by TTL or NIM signals at any repetition rate from <1 Hz and up to 80 MHz.

    Changes to the pulse repetition rate have an impact on the total average output power of the laser. As opposed to directly pulsed laser diodes, e .g., LDH series from PicoQuant, the pulse energy of the fiber amplified VisIR and VisUV modules is not constant for all repetition rates. Consequently, the average output power does not depend linearly on the repetition rate.
