Effect of laser operating mode in paint removal with a fiber laser

An investigation on co-axial water-jet assisted fiber laser cutting of metal sheets

“…The laser beam delivery system is mounted on a 5-axis CNC work station capable to move at speeds up to 25 m/min. The complete details of laser system such as beam intensity profile and modulation of laser beam can be found elsewhere [22].…”

“…Apart from laser fluence the laser beam intensity profile also may play an important role in the defects. The utilised laser beam has a non-uniform intensity distribution with a central lob of high intensity and non-uniform outer annular bands of relatively low intensities [22].…”

Modification of bent angle of mechanically formed stainless steel sheets by laser forming

“…The intensity distribution of the laser beam was measured by Madhukar et al (2013). They obtained a stepped intensity distribution profile of the laser beam using apertures made of graphite having openings of increasing diameters.…”

A study on co-axial water-jet assisted fiber laser grooving of silicon

“…They are being adopted in cutting of thick (Wandera et al, 2009) and thin sheets (Baumeister et al, 2006) of various materials, cladding (Valsecchi and Previtali, 2013), welding (Bandyopadhyay et al, 2014), forming (Chakraborty et al, 2012), paint removal (Madhukar et al, 2013a), water-jet assisted laser paint removal (Madhukar et al, 2013b), surface hardening , underwater laser cutting (Mullick et al, 2013), and micromachining of Ti6Al4 V for bio medical applications (Mukherjee et al, 2013) etc. Therefore, an attempt has been made to use an Yb-fiber laser operating at 1.07 m wavelength for control grooving of silicon.…”
