Spectroscopy and mode-locking laser operation of Tm:LuYO3 mixed sesquioxide ceramic
Abstract:
Tm:LuYO3 mixed ceramic was successfully fabricated by the solid-state reactive sintering method. The absorption cross section and emission cross section were studied at room temperature. The fluorescence lifetime of 3F4 energy level was fitted to be 2.6 ms. A continuous-wave (CW) laser operation of Tm:LuYO3 ceramic, pumped at 796 nm, was realized with the output power of 1.2 W and slope efficiency of 25.1%. A mode-locking (ML) laser operation of Tm:LuYO3 ceramic was demonstrated for the first time with pulse duration of 41 ps and pulse repetition frequency of 139.3 MHz.

Modes of Operations of BJT
Active Mode: The most common mode for amplification, the active mode features a forward-biased emitter-base junction and a reverse-biased base-collector junction. This setup enables electrons to be injected from the emitter to the base while blocking the majority carriers at the collector. The...
