Lasers [PDF]

Annales de Dermatologie et de Vénéréologie, 2012
Lasers are a very effective approach for treating many hyperpigmented lesions. They are the gold standard treatment for actinic lentigos and dermal hypermelanocytosis, such as Ota nevus. Becker nevus, hyperpigmented mosaicisms, and lentigines can also be successfully treated with lasers, but they could be less effective and relapses can be observed ...

Efficient plasma electron accelerator driven by linearly chirped multi-10-TW laser pulses

Scientific Reports, 2023
The temporal rearrangement of the spectral components of an ultrafast and intense laser pulse, i.e., the chirp of the pulse, offers significant possibilities for controlling its interaction with matter and plasma. In the propagation of ultra-strong laser

High-power amplified spontaneous emission pulses with tunable coherence for efficient non-linear processes

Scientific Reports, 2021
We report on a detailed study of an amplified spontaneous emission source operated in a pulsed regime with particular attention paid to the influence of high-intensity chaotic temporal events on the generation of nonlinear processes. To this aim, we have
