Published: February 2012

We report the validation of the Diagonal Scan (D-Scan) technique to determine the incubation parameter for ultrashort laser pulses ablation. A theory to calculate the laser pulses superposition and a procedure for quantifying incubation effects are described, and the results obtained for BK7 samples in the 100 fs regime are compared to the ones given by the traditional method, showing a good agreement.

Transition metal nitrides have extensive applications, including magnetic storage devices, hardware resistance coatings, and low-temperature fuel cells. This study investigated the structural, electrical, and mechanical properties of thin zirconium nitride (ZrN) films by examining the effects of laser irradiation times. Thin ZrN films were deposited on glass substrates using pulsed DC magnetron sputtering and irradiated with a diode laser for 6 and 10 min.

Papulopustular rosacea is an inflammatory subtype of rosacea that can significantly impair patients' quality of life. Available treatment options range from anti-inflammatory topical and oral medications to laser and light therapies. Photodynamic therapy with aminolevulinic acid (ALA-PDT) has emerged as a more recent treatment option for papulopustular rosacea.

Objectives: To investigate the effectiveness of different holmium:yttrium-aluminum-garnet (Ho:YAG) laser modes for lithotripsy in the "dusting era" and identify the optimal laser mode for producing stone fragments measuring ≤0.5 mm.

Methods: We used plaster of Paris-made artificial stones crushed into 2-3 mm pieces, weighing 1 g in total.

Photobiomodulation (PBM) is a technology that has gained much attention in recent years regarding its potential application for stimulating wound healing, alleviating pain, reducing inflammation, and aiding in the restoration of function. Due to a scarcity of evidence in the literature regarding PBM for the treatment of burns, our objective of this study was to test whether treatment with PBM in hospitalized patients with second-degree burns accelerated recovery. A double-blind controlled study was conducted on nine patients with up to 15% second-degree burns who were hospitalized at Hadassah-Hebrew University Medical Center, Ein Kerem Campus, Jerusalem Israel, between July 2022 and November 2022.

Photoacoustic microscopy (PAM) is a high-resolution and non-invasive imaging modality that provides optical absorption contrast. By employing dual- or multiple-wavelength excitation, PAM extends its capabilities to offer valuable spectroscopic information. To achieve efficient multispectral PAM imaging, an essential requirement is a light source characterized by a high repetition rate and switching rate, a ≈microjoule pulse energy, and a ≈nanosecond pulse duration.
