The laser trabeculotomy is one of the new techniques using light as a surgical ability in the treatment of some ocular diseases. The trabecula, in fact, plays an important part in the absorption of the aqueous humor and its bad functioning is the reason for chronic glaucoma. Here are some results obtained on in vitro trabecula with YAG-neodymium laser and an argon laser, thus showing that it is necessary to have very good focussing if we want to obtain a drill on the trabecula without having an excessive laser power.

We investigate the enhanced terahertz generation in the organic crystal BNA when pumped by compressed high-energy ytterbium laser pulses. By compressing the pump pulses from 170 fs down to 43 fs using an argon-filled hollow-core fiber and chirped mirrors, the terahertz conversion efficiency is increased by 2.4 times, leading to the generation of multi-microjoule terahertz pulses with a frequency spectrum almost twice as wide, extending up to 19 THz.

In this Letter, inert element (helium and argon for specific)-doped black silicon is obtained by helium ion-implantation followed by femtosecond pulse laser irradiation in an argon atmosphere based on near-intrinsic silicon substrates. Within the 200 nm of the silicon surface, the concentrations of helium and argon are both above the order of 10 cm.

Femtosecond lasers represent a novel tool for tattoo removal as sources that can be operated at high power, potentially leading to different removal pathways and products. Consequently, the potential toxicity of its application also needs to be evaluated. In this framework, we present a comparative study of Ti:Sapphire femtosecond laser irradiation, as a function of laser power and exposure time, on water dispersions of Pigment Green 7 (PG7) and the green tattoo ink Green Concentrate (GC), which contains PG7 as its coloring agent.

Vitiligo is a chronic depigmenting condition that causes amelanotic macules and patches on the skin. Despite various treatment options, treating vitiligo is a challenge. This study aimed to evaluate the combination of laser CO fractional and narrow-band ultraviolet B (NB-UVB) versus NB-UVB monotherapy in vitiligo patients.

Background: Post-inflammatory hyperpigmentation (PIH) is a common cosmetic concern, often leading to significant psychological distress for the patients. With the widespread application of lasers including ablative fractional resurfacing (AFR) with a 10,600 nm CO laser, PIH caused by lasers is becoming increasingly common. But due to the absence of an appropriate animal research model, our understanding of pathophysiological mechanisms and preventive strategies for PIH remains limited.
