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 Picosecond Laser for Nonmechanical Laser in situ Keratomileusis
Journal of Refractive Surgery, 1998ABSTRACT PURPOSE: To introduce the clinical use of the Nd:YLF picosecond laser as a nonmechanical microkeratome. METHODS: A commercially available Nd:YLF picosecond laser (25 µJ/pulse, 30 psec, 1053 nm) was used to deliver intrastromal pulses of focused high power laser light to generate a flap for laser in situ keratomileusis ...

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 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.

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.

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.

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 ...
