Abstract

The dynamic behaviour of long monolithic modelocked lasers for the emission wavelength 1.06 μm containing an active gain section and a passive cavity section was simulated. Numerical tools have been used to solve the travelling wave and carrier rate equations taking into account the effect of gain dispersion. Different configurations and arrangements including an absorber section and a section with a DBR were studied and compared. Best pulses are achieved with a configuration having a saturable-absorber section at the front facet. Peak powers of more than 5 W, pulse energies greater then 15 pJ and time-bandwidth products less than 0.5 are obtained by optimising the resonator configuration.
