Femtosecond Laser Micromachining A Back To Basics Primer

Lensx cataract femtosecond alcon system free board ship ship. Development of deep ultraviolet duv excimer laser lithography by ibm in 1982 was a critical milestone that led to the wide acceptance of excimer laser micromachining as it offered a reduced heat affected zone haz speed and versatility across a range of operations including ablating drilling cutting and welding.

The pico and femtosecond laser micromachining has grown up as a reliable tool for precise manufacturing and electronic industries to make fine drilling and machining into hard metals and ceramics as well as soft plastic and to form various nano and microtextures for improvement of surface functions and properties in products.

Femtosecond laser micromachining a back to basics primer. Many of these advantages are particularly useful for the manufacture of medical materials such as coronary stents see fig. Lonnie lucas and jim zhang applied energetics femtosecond laser micromachining. Ondax picopulse optigrate braggrate ultrafast femtosecond cpa laser chirped vbg ondax picopulse optigrate 260000. Laser micromachining delivers a range of precision laser processes for laser drilling micro drilling micro hole drilling laser cutting micro cutting laser milling laser micro milling laser welding and surface treatments that apply to precision micro machining and micro engineering requirements across a wide range of industries. The latest tweets from applied energetics at aelaser. A back to basics primer eloz. At a high laser flux the material is converted to the plasma state and melt ejection takes place. This article has provided a back to basics description of ultrafast laser microprocessing from laser sources and basic mechanisms to potential applications. Applied energetics develops and manufactures ultrafast lasers high voltage electron beam systems and other applied energy systems for commercial applications. The latest method that further advances laser material processing at the. Although many superior applications of ultrafast laser micromachining have been found over conventional laser processing its advantages and potential uses need to be further explored. By integrating the film sa in a laser cavity a stable pulsed laser appeared. Picopulse braggrate optigrate ondax ultrafast vbg laser cpa femtosecond chirped chirped femtosecond cpa picopulse ultrafast vbg braggrate laser ondax optigrate. We report for the first time the application of lutetium oxide lu 2 o 3 thin film as a saturable absorber sa in generating a stable and compact q switched erbium doped fiber laser edfl operating at 1570 nmthe film sa was prepared by embedding the lu 2 o 3 particles into a polyvinyl alcohol pva host film. The rate of energy delivery from an ultra short pulsed in the picosecond and femtosecond regime laser beam into the near surface regions of a solid involves extremely short periodic electronic excitation and de excitation.

Laser cutting system is now one of the key fabrication technologies used for coronary stent manufactureactually it is the most effective method in processing stents as compared to other traditional methods.
