Abstract
A new scheme for travelling wave excitation of amplified spontaneous emission (ASE) and distributed feedback dye laser (DFDL) is presented. The method is based on the proper tilt of pumping pulse fronts by using diffraction gratings. ASE pulses emitted in the forward direction have shown a considerable pulse shortening (up to twofold) with respect to the pump duration. Travelling wave DFDL operation was also demonstrated. DFDL pulse shortening to below the resolution of the streak camera system (1.9 ps) was observed. Simultaneous measurement of the pulse spectrum and consideration of the time-bandwidth product has led to an estimate of the pulse duration Tp= 0.4 ps.
