The laser scalpel and the laser coagulator are representative in laser medicine. However the biostimulative effect of laser with low power is getting the focus of attention, since acceleration of wound healing has been proved by laser radiation. Recently laser acupuncture was initiated as an unique therapeutic application in Europe and China. In Japan the authors have developed YAG laser acupun...

BACKGROUND Conventional short-pulsed Er:YAG lasers show less effective hemostasis and weak photothermal damage on papillary dermis. Recently, newer long-pulsed Er:YAG laser systems has been developed. OBJECTIVE To evaluate the clinical and histologic effects of long-pulsed Er:YAG laser resurfacing for pitted facial acne scars. METHODS Thirty-five patients with pitted facial acne scars were ...

Abstract It is well known that the surface topography of a part can affect its mechanical performance, which typical in additive manufacturing. In this context, we report about modification manufactured components made Titanium 64 (Ti64) and Scalmalloy ® , using pulsed laser, with aim reducing their roughness. our experiments, nanosecond-pulsed infrared laser source variable pulse durations bet...

Fujikura has achieved an output power of 30 W from a Q-switched pulsed fiber laser with a pulse width about 100 ns for the first time in the world. Following the achievement, we commercialized a 70 W output pulsed fiber laser . In the article, we describe our activities on high-power pulsed fiber lasers, and introduce our 70 W output products. Fujikura’s advanced and original functions of pulse...

Laser (or light) hair removal, also referred to as photoepilation, is the most commonly used laser or light-based cosmetic medical procedure. The extended theory of selective photothermolysis is the basic principle for destruction of hair follicles using light. In this type of laser application the chromophore is follicular melanin. Several types of lasers and light sources have been effective ...

In this paper we have studied the effect of magneto-static field onpropagation of thermal wave generated in metal by pulsed laser. In fact this interactiongenerate acoustic wave in different mechanisms. However, always the commonmechanism in the interactions of laser pulse and metal is the thermo-elastic wavegeneration. Applying the suitable magneto-static field on the s...
