Picosecond substructure of laser spikes
IEEE Journal of Quantum Electronics, 1968The two-photon fluorescence technique has been used to examine, on a picosecond time scale, the output of a long-pulse (non-Q-switched) Nd:glass laser. The well-known ``spikes,'' about 200 nsec wide, are found, in many cases, to consist of a large number of ultrashort pulses, about 3 psec in duration.

Picosecond lasers in micromachining
ICALEO 2003: 22nd International Congress on Laser Materials Processing and Laser Microfabrication, 2003Recent improvements to mode-locked lasers with picosecond pulse duration have fueled an increased interest for industrial applications, especially micromachining. Short pulses offer advantages for ablation of various materials. Reduced thermal load, low ablation threshold and other advantages of shorter pulses need to be tested for real application.

In recent years, experimental investigations of vibrational relaxation processes have received increasing attention. Interesting information is obtained from the band shapes observed in infrared and Raman spectroscopy [1, 21. The interpretation of the measured lines is difficult, however, since several physical processes contribute in general to the ...

CLEO: 2014, 2014
Short-pulse-pumped optical parametric chirped pulse amplification (OPCPA) demands powerful picosecond lasers with high average powers and high pulse energies. We report on the current picosecond thin-disk amplifiers development and their applications in research.

Picosecond visible Raman lasers
Advanced Photonics & Renewable Energy, 2010We present a technique that enables the efficient generation of picosecond laser pulses across the spectrum based on Raman crystals. The results are supported by a model that is in perfect agreement with the experiments.

Calorimeter for Picosecond Laser Pulses
Applied Optics, 1973Calorimeters have been designed and constructed that can measure the energy content of picosecond 1.06-microm laser pulses ranging in energy from ~13 microJ to 200 J. Noise levels are approximately 55 dB below individual instruments' upper limits. The thermopile output voltage peaks in less than 2 sec and recovers with a time constant of ~50 sec or ...

Applied Physics B Photophysics and Laser Chemistry, 1991
A novel method for the pulse shortening of the 578 nm spectral line from a CuBr laser is proposed in this paper. By amplifying a seeded picosecond dye laser through the active medium of a CuBr laser, nearly Fourier-transform-limited picosecond pulses of the CuBr laser have been obtained and the output characteristics are also investigated in detail.

Picosecond dye laser pumped by an excimer laser
Applied Optics, 1985A XeCl excimer laser-pumped dye laser generating 40-psec long pulses with 2.5-MW peak power, operating at 382 nm with 10-pps repetition rate is described. Short-pulse generation is achieved by cascade pumping of a quenched dye laser. The laser is simple and versatile. The possibilities of further developments are also discussed.
