The two parts are joined when the melt zone is produced at the contact interface. In conventional infrared laser welding of plastics, the so-called Through Transmission Infrared (TTIr) laser welding has been focused on (Grewell et al., 2003). WebUltrafast lasers. Ultrafast lasers are generally defined as lasers that produce pulses in the range of 5 fs to 100 ps (1 femtosecond = 10 −15 seconds). If a laser is able to oscillate in many longitudinal modes, such short pulses can be produced with the so-called mode-locking technique. green cities forterra
