Science (New York, N.Y.), 1976
The ability to directly measure and evaluate ultrafast processes with unprecedented time resolution and reliability has greatly extended our knowledge about the kinetics of primary processes in chemistry and allied physical and biological sciences. Improvements in the reliability and versatility of picosecond techniques should lead to an increase in ...

Advances in Picosecond Spectroscopy
Science, 1982Progress in the technology of picosecond spectroscopy in the past few years has made possible the generation of well-characterized pulses emitted by synchronously pumped tunable dye lasers. In addition, the development of sensitive emission and absorption detection methods and the advent of picosecond Raman and coherent anti-Stokes Raman spectroscopy ...

Applied Physics Letters, 1972
A simple off-axis hologram has been recorded on thin bismuth film using a train of picosecond pulses from a mode-locked Nd: glass laser. Due to the ultrashort pulse duration and temporal coherence length of the laser, a time-of-arrival principle is utilized to show the correspondence of a point on the hologram to some specific region of the object.

Picosecond spectrochronography
IEEE Journal of Quantum Electronics, 1983The general problem of extracting complete (amplitude and phase) information out of an optical signal is discussed. The authors have shown that the best one can do to determine all essential features of light pulses is to apply simultaneous temporal and spectral analysis to take spectrochronograms with the appropriate shape of the resolution cell on ...

Transient picosecond photoconductivity in polyacetylene
Physical Review B, 1993We present the results of transient photoconductivity measurements on highly oriented trans-polyacetylene. Using a photoconductive switching method utilizing picosecond optical pulses we have improved the temporal resolution of the photoresponse by one order of magnitude. We observe a fast temperature-independent photocurrent, which decays within a few

The extremely active interest in recent years in the study with picosecond pulses of nonlinear optical effects can be accounted for by a number of reasons. First, the peak power available from modelocked laser and laser amplifier systems greatly exceeds that obtainable from Q-switched and other longer pulsed lasers.

The picosecond laser for tattoo removal
Lasers in Medical Science, 2016The prevalence of tattoos continues to grow as modern society's stigma towards this form of body art shifts towards greater acceptance. Approximately one third of Americans aged 18-25 and 40 % of Americans aged 26-40 are tattooed. As tattoos continue to rise in popularity, so has the demand for an effective method of tattoo removal such as lasers.

The technology for generating and detecting electromagnetic waves has evolved significantly over the last 120 years. In the early 1890s, Guglielmo Marconi used a spark-gap transmitter to build a wireless telegraphy system. In his design, he charged a capacitor to a high dc voltage and connected it to a parallel combination of an inductor, a second ...
