Commonly used pulsed lasers are nanosecond, femtosecond, and picosecond lasers. A pulsed laser produces short pulses with a short interaction time with the material, which can largely avoid impact on the thermal movement of molecules and has a minimal thermal impact on the surrounding materials, thus having significant advantages in precision microfabrication. It is now widely used in flexible electronics, chips, medicine, and other fields, such as photographic resin curing, microwelding, vision correction, heart stent manufacturing, etc. However, as an emerging processing technology, the application prospects of pulsed lasers have yet to be fully expanded, and there is still a need to continuously explore the mechanisms of interaction with materials, to manufacture advanced functional structures, and to develop advanced process technologies.Technology: general issuesbicssccontact spacerdermatologyEBSDelectrodeselectrolytehardnesslaryngologylaser diodeslaser micro-cuttinglaser photothermal ablationlaser processinglaser structuringlaser surface texturinglaser weldingmedical applicationsmicrostructuren/aODS Euroferoxide dispersion strengthened steelPET filmPI filmpulsed and continuous wave (cw) regimesspread areatactile sensortemperature fieldtransparent polymerultraviolet nanosecond pulse laserwettabilitywetting timeZr-based metallic glassTechnology: general issuesRong Youminedt1293628Wu CongyiedtHuang YuedtRong YouminothWu CongyiothHuang YuothBOOK9910557528403321Advanced Materials, Structures and Processing Technologies Based on Pulsed Laser3022679UNINA
