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.
