A rapidly tunable (520−680 nm) narrow-bandwidth ps-laser pulse source based on a 1030 nm 80 MHz oscillator — •Lukas Ebner, Martin Josef Winterhalder, and Andreas Zumbusch — Universität Konstanz

In optical spectroscopy the bandwidth of the light directly defines the spectroscopic resolution. We present a method to generate narrow bandwidth ps-laser pulses with a rectangular shape featuring sharp edges in the time domain. To this end we use the soliton fission of a 250 fs laser pulse at 1030 nm in a photonic crystal fiber (PCF) to generate a soliton at around 1300 nm. By frequency doubling this soliton in a periodically poled lithium niobate (PPLN) crystal, we obtain the narrow bandwidth rectangular ps-pulses between (520−680 nm). Tunability is given by employing a fan out PPLN with different poling periods.
