Study on Polishing DF2 (AISI O1) Steel by Nd: YAG Laser

Optimization of Operating Parameters for Autogenous Welding of AISI 316L Stainless Steel and Steel Using Pulsed Nd: YAG Laser

An attempt made to optimize the operating parameters involved in an autogenous pulsed Nd: YAG laser welding process of similar and dissimilar combinations of butt joint of 2 mm thick 316 L stainless steel and mild steel. Influence of prominent laser welding parameters such as average peak power, defocus position, spot position, and shielding gas were investigated for welded joints considered. T...

Subdermal Nd-YAG laser for axillary hyperhidrosis.

BACKGROUND Axillary hyperhidrosis is a common but difficult-to-treat condition with major social, labor, and emotional consequences. OBJECTIVE The aim of this study is to present the Nd-YAG laser as a safe and effective option for the treatment of axillary hyperhidrosis. MATERIALS AND METHODS From January 2002 to April 2007, 17 patients (15 women and 2 men) with axillary hyperhidrosis were ...

Endoscopic Nd : YAG laser treatment ofrectosigmoid cancer

Forty nine patients with rectosigmoid carcinoma considered unsuitable for surgery underwent endoscopic Nd:YAG laser treatment for paliiation of symptoms and tumour eradication, if feasible. Altogether 25 (51%) of the lesions had distal margins less than 7 cm from the anus and 36 (73%) extended above the peritoneal reflection. In seven patients with tumours less than 3 cm in diameter, symptomati...

Characterization of Nd: Yag Laser Radiation Effects on Ti6Al4V Physico-Chemical Properties: An In Vivo Study

The effect of a Nd: YAG laser (1064 nm) has been studied on Ti6Al4V alloy in terms of optical and physical parameters for biomedical applications. The superior surface microhardness hardness (i.e. 377 VHN) is attributed to grain refinement associated with laser melting and rapid solidification. The electrochemical property, mainly pitting corrosion resistance, has been carried out in Hanks salt...
