چکیده انگلیسی
A Q-switched thulium-fluoride fiber (TFF) laser using gallium selenide (GaSe) as a passive saturable absorber (SA) for operation in the S+/S band is demonstrated. The generated pulses can be tuned from 1454â¯nm to 1512â¯nm, giving a tuning range of 58â¯nm. At 1502â¯nm, stable Q-switching operation is obtained from a pump power of 76.2â¯mW and is observed until the maximum pump power of 133.6â¯mW is reached, with the repetition rate varying from 16.5â¯kHz to 33.3â¯kHz and having a narrowest pulse width at 2.7â¯Âµs. The highest pulse energy obtained in this work is 51.4â¯nJ and this is, to the knowledge of the authors, the first time that Q-switching operation in the S+/S band region is obtained from a TFF laser using a GaSe based SA.
