Tailor-made blanks are sheet metal assemblies with different thicknesses and/or materials and/or surface coatings. A monolithic sheet can be machined to make the required thickness variations that is referred as tailor machined blanks. Due to the thickness variation in tailor machined blanks, laser bending of these blanks is more complicated than monolithic plates. In this article, laser formin...

the minimal invasive nature of lasers, with quick tissue response and healing has made them a very attractive technology in various fields of dentistry which serves as a tool to create a better result than ever before. the rapid development of lasers and their wavelengths with variety of applications on soft and hard tissues may continue to have major impact on the scope and practice in prosthe...

Cavity-enhanced detection’-3 can be used as a sensitive means of monitoring laser-surface interactions. In particular, it can detect the amount of material ejected from a solidor liquid-film surface when a laser beam is focused onto it. The tiny ablation plume is monitored inside an optical cavity by a fixed frequency continuous-wave (cw) probe beam. The photovaporization signal is produced by ...

Background: Low-level lasers are used for various medical applications including wound healing and hair loss treatment. Cell Therapy using skin stem cells could be a novel approach to hair transplantation. However, there is no study on the effect of low-level laser on the hair follicle stem cells. So, in this study, we investigated the effect of low level laser irradiation on viability and ROS ...

The vibrational bound states of the He(2)Ne(+) complex have been determined using a potential energy surface previously published by Seong et al. [J. Chem. Phys. 2004, 120, 7456]. The calculation was performed by sequential diagonalization-truncation techniques in a discrete variable representation using Radau hyperspherical coordinates. There are 52 bound levels. The ground state has an energy...

Background: The theory of selective photo-thermolysis led to the development of a variety of different laser systems which range from the shorter spectrum of 694nm ruby laser to the middle with the 755nm alexandrite and 810nm diode lasers to the long end with the 1064nm (Nd:YAG) laser. Objective: A systematic review on the clinical trials with use of various laser sources for hair removal...

An excited two-atom system can decay via different competing relaxation processes. If the excess energy is sufficiently high may not only relax spontaneous emission but also undergo interatomic Coulombic (ICD) or even Auger decay. We provide analytical expressions for rates by including them into same quantum optical framework on basis of macroscopic electrodynamics. By comparing in free space ...
