Paper Abstract

The erbium 2.7-micrometer fluorozirconate fiber laser is investigated in computer simulations and experiments. An output power of 158 mW at 2.7 micrometer is achieved from an erbium- doped single-mode fiber cascade laser. The output power is limited only by the pump power available from the Ti:sapphire laser. The slope efficiency of 23.3% in the cascade-lasing regime is close to the calculated limit of 27%. It is shown that this cascade regime represents the most efficient system for the operation of an erbium 2.7-micrometer fluorozirconate fiber laser.
