Arrangement for generating tunable picosecond light pulses in visible spectral range has optical extender for increasing pulse duration of frequency-converted light pulses to at least 1 picosecond

摘要

The arrangement has a laser system that emits femtosecond light pulses in the infrared spectral region and an optical frequency converter for converting the wavelength of the light pulses into the visible region. The wavelength of the light pulses emitted by the laser system can be tuned and an optical extender is provided with which the pulse duration of the frequency-converted light pulses can be increased to at least 1 picosecond.
