Pico And Femtosecond Laser Micromachining For Surface

We focus on laser micromachining of virtually any material using short pulse and ultra short pulse lasers as well as short wave lasers uv.

Laser beam micromachining. The high frequency of monochromatic light will fall on the surface then heating melting and vaporizing of the material take place due. This process uses thermal energy to remove material from metallic or nonmetallic surfaces. Direct writing mask projection and interference. A beam quality parameter is m2 number ow lp the minimum spot diameter of a beam dis given by d 4p m2 lfd for micromachining smallest spot size is obtained when m2 1. The melting of the target may depend on three main factors namely average power of the laser beam wavelength of the laser beam and intensity of the laser spot on the target 9. It consists of a laser source to emit ultra short pulses and a programmable galvanometer scanner to guide the beam accurately at high speed over the target. A typical laser micromachining system is shown in fig. Laser beam micromachining lbmm has revolutionized many industries by providing innovative. System is protected by class 1 equivalent laser safety enclosure and controlled through advanced sca engineer software window. This article demonstrates why laser beam shaping is necessary for microdrilling with ultrashort pulse lasers. Laser micromachining by ablation is an advantageous process for advanced manufacturing. The use of short and ultrashort laser pulses for micromachining application is an emerging technology. Because of our many years of experience in laser technology with solutions for production as well as in industry related research our machines achieve the best processing results in the um and sub um range. Direct writing is done by focusing the laser beam on the substrate. Laser beam micromachining lbmm has revolutionized many industries by providing innovative solutions in numerous industrial micro engineering.

Femtosecond laser micromachining system femtofab is a turnkey laser machine designed for specific industrial process. Based on this there are many different methods that use the laser for. Configuration is selected and carefully tuned according to a specific laser micromachining application. Laser machining can be done in three ways. Laser micromachining is the use of lasers for cutting drilling welding or to make other material modifications to achieve features on the single or double digit micrometer level. With a short wavelength and short focal length lens. Why laser beam shaping is necessary for microdrilling with ultrashort pulse lasers sami laroui. The laser beam is switched with a fast galvo shutter. A beam expansion telescope is used to increase the diameter of the beam. Laser beam shaping for innovative applications. For an ideal beam ow lpan invariant over the whole beam trajectory.
