Aim: To assess the performance and durability of beam expanders under prolonged exposure to specific laser wavelengths, ensuring their reliability in industrial laser micromachining applications.

Brief description: In collaboration with Beamera, a company specializing in the design and manufacture of optical components for laser applications, this project focused on characterizing beam expanders when subjected to continuous laser irradiation. The study involved two primary tests:

  1. Longevity Test at 355 nm: Utilizing a picosecond laser, the beam expander was exposed to 355 nm wavelength radiation. The transmitted power was monitored over time to detect any degradation in performance. Results indicated a ~13% decrease in transmitted power after 10 minutes of exposure.
  2. Transmission Test at 10.6 µm: Employing a CO₂ laser, the beam expander was tested at a 10.6 µm wavelength. Over a 12-hour period, no significant reduction in transmitted power was observed, demonstrating the component's resilience at this wavelength.

Benefits: The findings provide valuable insights into the operational limits and durability of beam expanders under different laser conditions. This information is crucial for optimizing the performance and longevity of optical components in laser micromachining processes, leading to more reliable and efficient industrial applications.
