Researches on Ti:S Laser to Producing 820 nm Band Laser Beam by Frequency-selecting with External Cavity
Ti:S激光器外腔选频产生820 nm带激光研究

The experimental results of Ti:S laser producing 820 nm band laser beam is reported by frequency-selecting with external cavity, which is formed by a piece of Tm:Ho co-doped single-mode silica fiber. The optical to optical conversion efficiency and the slope efficiency are 15.7% and 17.3%, respectively. This is the first report on the compound cavity Ti:S laser realized with rear-earth doped optical fiber as the external cavity. The relations between the measured output power and spectrum from the compound cavity Ti:S laser vs the launched pump power and fiber length are researched, and analysis is done accordingly.
