Patent number: 11691216Abstract: A method includes depositing a plurality of dopant particles within a predetermined region of a transparent material. The method also includes focusing a laser beam along an optical axis to a focal region that overlaps with at least a portion of the predetermined region. The focal region can irradiate at least a first dopant particle of the plurality of dopant particles. The method further includes adjusting a parameter of the laser beam to generate a plasma configured to form an inclusion within the transparent material. The method additionally includes scanning the focal region along a path within the transparent material to elongate the inclusion generally along the path.Type: GrantFiled: June 18, 2019Date of Patent: July 4, 2023Assignee: Avava, Inc.Inventors: Joseph Ting, Charles Holland Dresser, Jayant Bhawalkar

Patent number: 10914942Abstract: An electromagnetic beam scanning system and corresponding method of use is provided. The system includes a motor, a reciprocating mechanism, and a focus optic. The motor is configured to generate a rotational movement. The reciprocating mechanism is operatively coupled with the motor and configured to convert the rotational movement to a reciprocating movement including a plurality of strokes along a first scanned axis. The reciprocating movement has a constant speed over a portion of at least one stroke of the plurality of strokes. The focus optic is operatively coupled to the reciprocating mechanism such that the focus optic moves experiences the reciprocating movement of the reciprocating mechanism. The focus optic is configured to focus an electromagnetic radiation (EMR) beam incident upon the focus optic to a focus along an optical axis substantially orthogonal to the first scanned axis.Type: GrantFiled: April 17, 2020Date of Patent: February 9, 2021Assignee: Avava, Inc.Inventors: Charles Holland Dresser, Jayant Bhawalkar, Joseph Ting
