We describe a study of the laser drilling of stainless steel (SUS304) using a fiber laser with a
wavelength of 1090 nm, assisted by intermittent gas jets. By comparing with the results …

This study investigates the effect of six parameters in the repeatability of drilled holes in laser
percussion drilling process by means of statistical techniques. Peak power, pulse width …

Providing the technology to achieve an efficiency of 65% in natural gas-fired combined cycle
power plants is the aim of the German Collaborative Research Center 561 “Thermally highly …

In this paper, a machine vision-based system is used for in-situ monitoring and
characterization of the effect of swirling gas jet assisted laser percussion drilling. Feasibility …

This paper reports on etching rates and hole quality for nanosecond laser percussion drilling
of 200-μm thick 316L stainless steel performed with micro supersonic gas jets. The assist …

A systematic investigation was reported for observing and analyzing the process and

In this paper, a new form of combined pulsed laser (CPL) consisting of continuous wave
(CW) laser and nanosecond (ns) pulse train was proposed for drilling Q235B steel without …

Laser drilling is a non-conventional machining process which is widely used in automotive,
electronics and aerospace sectors to produce holes in diverse range of materials. Different …

In this work, the two main factors that influence the repeatability of the laser percussion
drilling process are identified. Experimental parametric analysis was carried out to correlate …

An experimental investigation was conducted to clarify the role of an assist gas during gas-
assisted laser-metal drilling for incident laser fluxes on the order of 106 W/cm2. In particular …
