The PicoEmerald S from APE – available from Photonics Solutions – combines a picosecond OPO and its pump laser in a single housing. The new pump source offers shorter pulses of 2 picoseconds with 10cm - 1 spectral width compared to the original PicoEmerald version offering 6 picoseconds. The selection of features make the PicoEmerald S well suited to CARS microscopy and SRS Raman microscopy.
