The PDL-808 Sepia is a multichannel picosecond diode laser available from PicoQuant GmbH. The modular system can drive up to eight laser heads in parallel in synchronous, delayed or user-defined sequence modes with up to an 80-MHz repetition rate. Laser heads for wavelengths ranging from 390 to 1550 nm are available. The system can achieve pulse widths as short as 70 ps, FWHM. Laser power and pulse width are adjustable from individual driver units. The signal path is established by external cabling that allows flexibility, jitter-free delay insertion and various synchronization options.
