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 ...

Dynamics of picosecond laser ablation for surgical treatment of colorectal cancer
Scientific Reports, 2020 Endoluminal surgery for the treatment of colorectal neoplasia is typically carried out using electrocautery tools which imply limited precision and the risk of harm through collateral thermal damage to the adjacent healthy tissue.

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).

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
