The lasers are based on a unique combination of gain-switched, fiber-amplified laser diodes with patented fiber pumping control and a state-of-the-art photonic-crystal fiber for supercontinuum generation. These lasers are computer-controlled through an easy to use graphical user interface for setting pulse repetition rate and wavelength selection. The tunable bandpass filter allows setting the emission wavelength to any value in the supercontinuum spectrum with spectral bandwidths between 3 and 15 nm. All variants can be operated at adjustable repetition rates and triggered through an internal oscillator, with six fixed rates between 2.5 and 40 MHz, or by an external source at any rate between 1 and 40 MHz. Depending on the emission wavelength, the temporal pulse widths range from 90 to 150 ps.
The laser is ideally suited for applications where flexible wavelength selection as well as high and variable repetition rates are important, such as time-resolved fluorescence spectroscopy, fluorescence anisotropy, single molecule detection, Fluorescence Correlation Spectroscopy (FCS), as well as for a variety of microscopy techniques.
