The Model cOPATMis a unique, three-beam source of ultrashort pulses at MHz repetition rate that operates in the 1-micron wavelength range. It is an ideal source for high repetition rate, 4-wave mixing experiments such as 3D multimodal imaging microscopy in cells and tissue. All three beams are synchronized to less than 10 femtoseconds. Two beams are independently tunable. At more than 100nJ/pulse, the Model cOPATMprovides enough energy to perform multi-modal microspectroscopy followed by ablative sectioning of tissue samples.
The Model cOPATMconsists of two synchronized optical parametric amplifiers (OPAs) in one enclosure pumped by our Model IMPULSETMMHz repetition rate, fiber laser oscillator/amplifier system2. Each OPA is independently tunable from 700 to 950nm in the signal range and from 1130 to 1300nm in the idler range. Residual 1030nm pump light of >1μJ is available from a separate output port. Motorized drives for electronic tuning are included. An optional wavelength extension is available providing tunability from 1125nm to 1950nm.
