GENERATING MULTIPLE BEAMS OF A HARMONIC FREQUENCY - A simplified explanation of the abstract

• This abstract for appeared for US patent application number 17804368 Titled 'GENERATING MULTIPLE BEAMS OF A HARMONIC FREQUENCY'

Simplified Explanation

The abstract describes a laser system that efficiently produces multiple laser beams of a higher frequency (harmonic frequency) from a lower frequency (fundamental frequency) beam. The system includes a laser that emits the fundamental frequency beam, a first stage that converts the fundamental frequency beam into a first-stage harmonic frequency beam and a first-stage residual fundamental frequency beam, and a second stage that further converts the residual fundamental frequency beam into a second-stage harmonic frequency beam.

Original Abstract Submitted

Examples are disclosed that relate to efficiently producing multiple laser beams of a harmonic frequency from a fundamental frequency beam. One example provides a laser system comprising a laser configured to output a fundamental frequency beam, a first harmonic-generation stage, and a second harmonic-generation stage. The first harmonic-generation stage is configured to receive an input of the fundamental frequency beam from the laser, and output from the laser system a first-stage harmonic frequency beam and a first-stage residual fundamental frequency beam. The second harmonic-generation stage is configured to receive an input of the first-stage residual fundamental frequency beam, and to output from the laser system a second-stage harmonic frequency beam.
