Diode-Pumped High Energy and High Average Power All-Solid-State Picosecond Amplifier Systems

open access: yesApplied Sciences, 2015
We present our research on the high energy picosecond laser operating at a repetition rate of 1 kHz and the high average power picosecond laser running at 100 kHz based on bulk Nd-doped crystals.

Experimental Investigations on Laser Ablation of Aluminum in Sub-Picosecond Regimes

open access: yesApplied Sciences, 2020
Due to high power and ultrashort pulses, femtosecond lasers excel at (but are not limited to) processing materials whose thicknesses are less than 500 microns. Numerous experiments and theoretical analyses testify to the fact that there are solid grounds

Application of photoelectric technology on melasma

open access: yesPifu-xingbing zhenliaoxue zazhi, 2022
Melasma is a skin disease where brown or pigmented patches appear on the face. Currently, it is difficult to be treated because of lower success rate and higher recurrence rate.

Application of Picosecond Laser in Dermatology

open access: yesBerkala 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.

Investigation of thermodynamic properties in picosecond laser-produced plasmas on silicon

open access: yesAIP 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

3.8-μm Mid-Infrared Laser Quasi-Synchronously Pumped by a MOPA Structured Picosecond Yb Fiber Amplifier With Multi-pulse Operation

open access: yesIEEE Photonics Journal, 2016
A picosecond pulsed mid-infrared laser with multi-pulse operation is experimentally demonstrated. This mid-infrared laser was composed of a fiber laser pumped optical parametric oscillator (OPO).

Comparison of Dopant Incorporation and Near-Infrared Photoresponse for Se-Doped Silicon Fabricated by fs Laser and ps Laser Irradiation

open access: yesCrystals, 2022
Se-doped silicon films were fabricated by femtosecond (fs) laser and picosecond (ps) laser irradiating Si–Se bilayer film-coated silicon. The surface morphology, impurity distribution, crystal phase, and near-infrared photocurrent response of fs-laser ...

Comparative treatments of a green tattoo ink with Ruby, Nd:YAG nano- and picosecond lasers in normal and array mode

open access: yesScientific 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.
