| Abstract: | Through optimisation of the spectrum and dispersion parameters of a synchronously mode locked Rhodamine B dye laser, pulses as short as  270 fs have been directly generated without using any saturable absorber or pulse compressor. In addition a system of tunable output coupling with well characterised dispersion has been demonstrated. |
