“…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.…”
