Design aspects of medical laser devices

Photodynamic Antitumor and Antimicrobial Activities of Free‐Base Tetra(4‐methylthiolphenyl)chlorin and Its Tin(IV) Complex

“…With the goal of identifying dyes suitable for treating infections that affect the skin and soft tissue layers, in vitro PACT studies with gram‐(+) Staphylococcus aureus ( S. aureus ) and gram‐(−) Escherichia coli ( E. coli ) bacteria were performed for 3 and 3‐Sn in a similar manner to the PDT activity experiments by using deep‐red region of the visible region (Thorlabs 660 nm LED). This facilitates enhanced penetration in the therapeutic window [19,20] . Optimization studies of the photosensitizer concentration were performed with 3‐Sn over a 75 min irradiation time, Figure S5.…”

Spectroscopic investigations of nanosized Cr3+ doped Sc2−xInx(WO4)3: A new promising laser material

“…Tunable solid‐state lasers have been studied for many years because of their wide field of application in medicine, military, industry, scientific research, telecommunications, environment, etc. . In near‐infrared (NIR) spectral area, among all investigated transitional active ions just a few possess efficient tunable laser emission, such as Ti 3+ in Al 2 O 3 ; Cr 3+ in BeAl 2 O 4, Gd 3 (Ga,Sc) 2 Ga 3 O 12, LiSrAlF 6 and LiCaAlF 6, as well as Cr 2+ in ZnSe and Cr 4+ in Mg 2 SiO 4 and Y 3 Al 5 O 12.…”

Recent Advances of Low-Level Light Therapy: Fundamentals, Efficacy and Applications

“…Lights (lasers and LEDs) have been used for various medical procedures such as dermatology and cosmetic surgery, wound healings, nerve stimulation, dentistry ophthalmology applications for vision corrections and corneal deceases, and many other therapeutic procedures [1][2][3]. Combining the nanoparticles, diode lasers have been also used for cancer therapy, bio-sensing, bioimaging, drug delivery, tissue engineering and diagnostics of cancer cell [4][5][6][7].…”

“…Therefore, near IR lasers are good candidates for procedures which need deep penetrations such as hair removal and nano-gold mediated cancer therapy [1]. On the other hand, visible lasers (430-680) nm with strong absorption in blood and color-dyes have been used for phototherapy of oral cancer, retina deceases and tattoo removal [2]. Mid-IR lasers (1.9-3.0) um and (9.3-10.6) um with strong absorption in water and tissue have been used for super surface procedures or ablative type procedures such as soft and hard tissue ablation.…”

“…Mid-IR lasers (1.9-3.0) um and (9.3-10.6) um with strong absorption in water and tissue have been used for super surface procedures or ablative type procedures such as soft and hard tissue ablation. Other IR lasers (1.3-1.6) um have been used for so called minimally invasive procedures such as resurfacing due to their smaller tissue absorption than that of mid-IR lasers [1,2].…”
