Application of Picosecond Laser in Dermatology
Berkala Ilmu Kesehatan Kulit dan Kelamin (Periodical of Dermatology and Venerology), 2023 Background: Lasers are one of the most important treatment modalities in dermatology. Lasers interact with chromophores through several mechanisms that depend on fluence and pulse durations.

The Review of Laser Engineering, 1988 A peak power of one terawatt has been obtained in XeCl with a pulse width of 310fs. Amplified spontaneous emission (ASE) was investigated extensively by changing the gain of wide aperture discharge amplifiers. As a result, the ASE content was suppressed to less than 3% in energy by using an appropriate spatial filter before the final amplifier along ...

Investigation of thermodynamic properties in picosecond laser-produced plasmas on silicon
AIP Advances, 2023 The validity of local thermodynamic equilibrium (LTE) in plasma is a long-term concern for laser-induced breakdown spectroscopy applications. In this paper, the spatial and temporal dependence of LTE deviation in picosecond laser-induced plasmas has been

Multi-wavelength, all-solid-state, continuous wave mode locked picosecond Raman laser [PDF]
, 2010 We demonstrate the operation of a cascaded continuous wave (CW) mode-locked Raman oscillator. The output pulses were compressed from 28 ps at 532 nm down to 6.5 ps at 559 nm (first Stokes) and 5.5 ps at 589 nm (second Stokes).

Scientific Reports, 2022 The tattoos removal has become an issue upon spread of the tattooing practice worldwide and hindsight regrets. Lasers are typically used for the purpose, though some colours such as green are considered “recalcitrant” to the treatment.
