Self-Pulsed Nanosecond 2.7- $mu ext{m}$ Solid-State Erbium Laser by Cooperatively Enhanced Reabsorption
The nanosecond self-pulsing operation candle snuffer big w of a midinfrared solid-state laser with no additional passive absorbers is reported in this paper.A proof-of-principle demonstration of the cooperatively enhanced reabsorption method, in which two laserdiode-pumped erbium gain media share the same laser resonator, is proposed.The two excite
