Abstract :
An all-optical inverter, which operates over a range of 15-1600 K, was demonstrated in an erbium-doped lutetium aluminum garnet crystal with 787.8, 787.8 and 790.1 nm laser diodes. In the case of 787.3 nm, the reversed-phase waveforms were obtained in a temperature range of 15-1100 K. In the case of 790.1 nm, they were observed in a temperature range of 850-1600 K. It has been confirmed that a mechanism of the phenomenon can be explained by calculating the rate equations based on an analytical model for a five-level system of the Er3+ ion
