In this work, laser ablation of a variety of materials including TBC superalloys used for aerospace has been demonstrated with a single mode fiber laser up to 400W. The paper will investigate the material removal rates and ablation quality.

This paper investigates laser percussion drilling of high quality holes for the aerospace market with a new low cost high peak power up to 16kW and high beam quality (M2=11) pulsed Nd: YAG laser especially developed for this application.

Aerospace gas turbines require a large number of small diameter holes (<1mm) to provide cooling in the turbine blades, nozzle guide vanes, combustion chambers and afterburner.

The high power heat source produced by a laser beam is ideal for surface modification. Laser heating produces local changes at the surface of the material whilst, leaving the properties of the bulk of a given component unaffected.

Microwelding perofmance comparison between a low power (125W) Pulsed ND: YAG Laser and a low power (100-200W) single mode Fiber Laser

YAG Laser - Increase weld speed, weld penetration and reduced porosity with supermodulated output power.

This paper investigates how zero width cutting methods surpass the traditional cutting methods, utilising references from C Hermanns, VS Konratenko, H Ostendarp & PTG Europe...
