Publication number: 20210023658Abstract: The present disclosure relates to a laser-based system and method for providing efficient melt removal of material from a surface of a material sample being acted on in a laser machining operation. In one implementation the system may make use of a continuous wave (CW) laser for generating a laser beam directed at a spot on the surface of the material sample. The CW laser may be configured to be modulated at a predetermined frequency such that the laser beam excites and amplifies surface capillary waves on the surface of the sample up to a melt ejection point, which ejects molten material from the spot being acted on by the laser beam, to more rapidly facilitate material removal from the spot.Type: ApplicationFiled: March 22, 2019Publication date: January 28, 2021Applicant: LAWRENCE LIVERMORE NATIONAL SECURITY, LLCInventors: Sonny S. LY, Jeffrey D. BUDE, Gabriel Mark GUSS, Wesley John KELLER, Raluca A. NEGRES, Alexander M. RUBENCHIK, Nan SHEN

Publication number: 20210001427Abstract: The present disclosure relates to a laser system for processing a material. The system may make use of a laser configured to intermittently generate a first laser pulse of a first duration and a first average power, at a spot on a surface of the material being processed, and a second laser pulse having a second duration and a second peak power. The second duration may be shorter than the first duration by a factor of at least 100, and directed at the spot. The second laser pulse is generated after the first laser pulse is generated. The first laser pulse is used to heat the spot on the surface of the material, while the second laser pulse induces a melt motion and material ejection of molten material from the melt pool.Type: ApplicationFiled: March 22, 2019Publication date: January 7, 2021Applicant: LAWRENCE LIVERMORE NATIONAL SECURITY, LLCInventors: Sonny S.
