Abstract

Production of ultrashort pulses at various wavelengths is generally based on mode locking techniques and, for practical applications, often requires the combined use of two expensive pump lasers, one CW, one pulsed. Other ways have been studied to produce short pulses using cavity transients, distributed feedback or cavity competition processes (1). In this work we report progress in a new technique, recently proposed (2), for obtaining high power ultrashort pulses from dyes using a single standard nanosecond pump laser.
