The output power, tuning and temporal behavior of the green (539-550 nm), Ho-doped fluorozirconate glass (ZBLAN) fiber laser pumped in the red (λ ∼ 643 nm) has been examined in detail. Fibers ranging in length from ∼20-86 cm have been studied, and more than 38 mW of output power has been obtained from a 21 cm long fiber for 30% output coupling and 280 m W of absorbed pump power. By inserting two prisms into the optical cavity, the oscillator has been tuned over ∼11 nm, and the emission spectrum of the free-running laser has been recorded as a function of pump power at both room temperature and 77 K. The self-pulsing (spiking) behavior of the laser and the influence of depletion of the Ho3+ ground state (5I8) population on the emission spectrum and efficiency of this system are discussed.
