  • Energy beam input to atom probe specimens from multiple angles
    Patent number: 11340256
    Abstract: An atom probe directs two or more pulsed laser beams onto a specimen, with each laser beam being on a different side of the specimen, and with each laser beam supplying pulses at a time different from the other laser beams. The laser beams are preferably generated by splitting a single beam provided by a laser source. The laser beams are preferably successively aligned incident with the specimen by one or more beam steering mirrors, which may also scan each laser beam over the specimen to achieve a desired degree of specimen ionization.
    Type: Grant
    Filed: January 31, 2018
    Date of Patent: May 24, 2022
    Assignee: Cameca Instruments, Inc.
