This paper discusses the use of high power lasers in the manufacture of microelectromechanical systems (MEMS). The ability to process a wide range of materials, and to produce truly three-dimensional structures with tolerances at the micron or sub-micron level, give laser micromachining some key advantages over other more established micromachining techniques. Previous work in this area is revi...

We read with interest the article by WARTH et al. [1] on mediastinal angiomyolipoma and tuberous sclerosis. Apart from mediastinal angiomyolipoma, lymphangioleiomyomato-sis (LAM) can occur as part of the genetic condition tuberous sclerosis [2]. Since the first report by CORNOG and ETERLINE [3], LAM has been increasingly studied for the pathological processes involved in atypical smooth muscle ...

Laser ablation of Ta plates using nanosecond optical vortex pulses was carried out, for the first time. It was suggested that owing to orbital angular momentum of optical vortex, clearer and smoother processed surfaces were obtained with less ablation threshold fluence, in comparison with the ablation by a nonvortex annular beam modified from a spatially Gaussian beam.

In order to service and grow in the present day of global competition, every manufacturing concern focuses mostly on two factors i.e. productivity and quality. Laser drilling is a popular non-traditional machining technique for producing large numbers of cooling holes of various sizes (less than mm diameter) and angles in modern aerotech components such as turbine blades, injector nozzles, and ...

The world of manufacturing has shifted its level to the era of space age machining. The purpose of this investigation is to develop Fuzzy based Graphical User Interface (GUI) for modeling of laser machining conditions. The developed fuzzy based GUI is expected to overcome the major problems faced by most of the manufacturing industries nowadays with the increased number controllable parameters ...

Laser– assisted permanent hair removal iscommonly performed for the treatment of unwantedhair. This procedure is usually associated withpain and pain reduction has an important role inthe success of this treatment. A common methodof reducing pain is to use topical analgesics . Amixture of lidocaine and prilocaine (EMLA) is acommonly used and very effective topical anesthetic.Another agent is di...
