A systematic study of microscopic many-body dynamics is used to analyze a strategy for how to generate ultrashort mode locked pulses in the vertical external-cavity surface-emitting lasers with a saturable absorber mirror. The field propagation is simulated using Maxwell's equations and is coupled to the polarization from the quantum wells using the semiconductor Bloch equations. Simulations on the level of second Born-Markov are used to fit coefficients for microscopic higher order correlation effects such as dephasing of the polarization, carrier-carrier scattering and carrier relaxation. We numerically examine recent published experimental results on mode locked pulses, as well as the self phase modulation in the gain chip and SESAM.
