Stable operation of a synchronously pumped colliding-pulse mode-locked ring dye laser.
Pulses of 100-fsec duration are obtained by synchronous pumping of a colliding-pulse ring dye laser with a mode-locked Ar(+)-ion laser. Stable operation of the synchronously pumped colliding-pulse mode-locked laser over hours was obtained by a suitable choice of the distance between the gain and the absorber in combination with an appropriate pump-pulse sequence.
متن کاملReciprocal passive mode locking of a rhodamine 6G dye laser and the Ar(+) pump laser.
A rhodamine 6G dye laser, internally pumped within the extended cavity of an Ar(+)-ion laser, is mode locked when its cavity length is matched to half that of the pump laser: the 5145-A argon laser line is passively mode locked by the combination of the saturable absorption and the lasing action of the dye, which is in turn synchronously pumped and mode locked. Tunable (5650-5950-A) ~10 psec pu...
متن کاملMode-locked deep ultraviolet Ce:LiCAF laser.
We report mode-locked operation of a synchronously pumped Ce:LiCAF oscillator. The laser operated in the deep UV with output radiation centered at 291 nm and a pulse duration of 6 ps. The maximum output power measured was 52 mW, with 13% slope efficiency. The Ce:LiCAF crystal has a gain bandwidth capable of supporting few-femtosecond pulses, and so our results demonstrate the potential to form ...
متن کاملPulse Structure Studies and Absolute Cavity Length Determination for a Synchronously Pumped Picosecond Dye Laser
Second harmonic cross correlation functions of a pulse with its near neighbor have been studied in a synchronously pumped cw dye laser. Measurements were made both as a function of dye laser cavity length mismatch and the number of cavity round trips separating the correlated pulses. The pulse envelope is found to have a characteristic interpulse frequency determined by the pump laser, whereas ...
متن کاملUltraviolet Picosecond Pump-probe Spectroscopy with a Synchronously Pumped Dye Laser. Rotational Diffusion of Diphenyl Butadiene
Over the last few years synchronously pumped dye lasers have been used to study a range of relaxation processes [1]. The wide wavelength tunability available gives an important advantage over passively mode-locked systems [2,3] when sub-picosecond time resolution is not required. In order to study smaller molecules more amenable to theoretical description it is important to extend the high repe...
