Abstract
LiSAF crystals (LiSrAlF6 doped with Cr3+ ions) are very interesting amplifier materials due to a large fluorescence bandwidth in the near infrared (800 nm to 1 μm) and an absorption band in the red (600-700 nm). Commercial high power single-stripe laser diodes emitting in this wavelength band are available since a few years. In the field of ultrashort pulses, there is a great interest to develop compact, all solid state diode-pumped ultrafast lasers. Lasers based on LiSAF crystals have the potential to replace Argon-pumped Ti:Sapphire femtosecond lasers for applications where the average power is limited to around 100 mW (seeding an amplifier for example).
