Yb CaF2 Laser Materials - Long Fluorescence Lifetime Low Dispersion Behavior

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.
