This study introduces a new multirod solid-state laser configuration. It achieves tenfold stabilization of the output beam diameter by managing thermal lensing effects in diode-pumped systems.

Area of Science:

  • Optics and Photonics
  • Laser Physics
  • Materials Science

Background:

  • Solid-state laser systems are crucial for various applications.
  • Thermal lensing is a significant challenge affecting laser beam quality and stability.
  • Existing methods for thermal lensing compensation can be complex or limited.

Purpose of the Study:

  • To propose and validate a novel configuration for multirod solid-state lasers.
  • To stabilize thermal-lens-dependent variations in output-beam parameters.
  • To enhance the beam diameter stability of high-power laser systems.

Main Methods:

  • A new multirod solid-state laser configuration is designed.
  • The laser beam is extracted from the collimating point of periodic beam propagation.
