Researchers designed astigmatism-free triangular resonators using the ABCD matrix method. A frequency-doubled Nd ring laser was built, demonstrating a single longitudinal mode with a circular Gaussian beam.

Area of Science:

  • Optics and Photonics
  • Laser Physics
  • Resonator Design

Background:

  • Triangular resonators are utilized in various laser systems.
  • Controlling beam waist and astigmatism is crucial for laser performance.
  • Previous designs often faced challenges with beam quality and stability.

Purpose of the Study:

  • To determine beam waist magnitudes and locations in sagittal and tangential planes for triangular resonators.
  • To develop design criteria for astigmatism-free beams in equilateral and isosceles triangular resonators.
  • To experimentally validate the design with a practical laser system.

Main Methods:

  • Utilized the ABCD matrix method for optical resonator analysis.
  • Analyzed both equilateral and isosceles triangular resonator geometries.
