Operation features of the erbium fiber lasers with short cavities near two phase transitions have been established experimentally for the first time. The power-law behavior of the system parameters in the vicinity of the critical point in a wide range of pump power values was revealed. The parameters and operation regimes dependence on the cavity length and pump power, namely the switching from pulsed to CW operation, was investigated. The pulse duration and frequency dependencies with varying cavity length have been investigated, which made it possible to experimentally establish the universal dependence of these parameters on the lasing power for passively Q-switched erbium fiber lasers. The critical indices for pulsed operation of the erbium fiber lasers are determined weakly depending on the cavity parameters. The results of the study can be used for designing high-coherent fiber laser sources.
