Synchronously Pumped Tunable Picosecond Dye Lasers

The synchronously pumped Gropius dye laser is a simple and versatile source for tunable picosecond and sub-picosecond pulses in the VIS to NIR range. The term synchronous pumping refers to matching the cavity round-trip time of the dye laser to an integer multiple of the mode-locking frequency. The resulting output from the Gropius is a train of pulses at 80 MHz repetition rate which can be tuned over a wide spectral range.
