Description

Description

Due to the toughness and the flexible and cheap production process, CaF2 has been used in many substrate materials for laser crystals. As an amplifying ion, Yb3+ also allows a three-level laser scheme, leading to low quantum defects and a significantly longer fluorescence lifetime. Yb3+:CaF2 can also provide a high optical efficiency and high output powers due to the reduced thermal load. Recently, ytterbium-doped alkaline-earth fluoride is mostly used in diode-pumped femtosecond laser and amplifiers. Alkaline-earth fluorides which can be easily grown by using the standard Czochralski or Bridgman technique show a great potential in the wide transmission range, high damage threshold and low dispersion behavior.

Features

  • Low quantum defect
  • High damage threshold, good thermal conductivity
  • Long fluorescence lifetime
  • Low dispersion behavior
  • Broad absorption bandwidth
  • Limited nonlinear effects under intense laser irradiation

Applications

  • High power ultrafast thin-disk oscillators
  • Passively mode-locked oscillators
  • Solid state tunable laser
