The Sepia PDL 810 system is a single channel pulsed diode laser driver system that allows operating a connected laser head in either pulsed or continuous wave (CW) mode. The driver may trigger the laser autonomously from its built-in crystal oscillator or, if a more complex triggering scheme is needed, can also be triggered by an external signal. Any output frequency from single shot (if triggered externally) to 80 MHz is supported.
Take full control
The operating parameters of the Sepia PDL 810 laser driver (such as trigger source, repetition rate, and pulse energy) are completely configured from a computer via USB, allowing for a quick set-up and easy storage of predefined set-ups. Stand-alone operation is possible, if no changes to the parameter set-up is required.
