Mode-Locked Fiber Lasers

Jean-Michel Ménard

Fiber laser now compete directly in several domains with semiconductor sources, 
over which they present the advantage of high brightness, excellent mode 
quality, highly efficient coupling into single-mode fiber, and a far superior 
wavelength stability with temperature.  
Furthermore, mode locked fiber lasers are capable of producing pulses with 
widths form close to 20fs to 1 ns at repetition rates, ranging from less than 1 
MHz to 100GHz.  This versatility, as well as the compact size of optical 
fibers, is quite unique in laser technology. 
During my talk I will firstly explain some of the different types of optical 
resonators for the cw rare earth doped fiber laser.  After that, I will give an 
overview on one type of ultrafast fiber laser system: the passively mode-locked 
single-mode fiber oscillator.  Finally some of the practical issues in the 
construction of mode-locked fiber laser and the applications of such laser 
systems will be discussed.
