Description

Yb:YAG crystal possesses many attractive laser characteristics including high quantum efficiency, no excited state absorption and upconversion loss, long radiative lifetime of the upper laser level, large absorption width, broad emission width, good optical, thermal and mechanical properties, so it is considered as the most potential gain for high efficiency, high power diode-pumped solid-state lasers.

Features

  • Wide absorption bandwidth
  • Low lasing threshold
  • High slope efficiency
  • Large luminescence cross-section
  • Linearly polarized emission and single-mode output

Applications

  • Model-locked laser
  • Laser welding
  • Laser cutting
  • Laser marking
