Abstract: A saturable absorber is an optical device that exhibits an intensity dependent transmission. What this means is that the device behaves differently depending on how intense the light that passed through it. In this study, the low power diode laser pointer was passed through a Rhodamine B solution. This solution which has a property of saturable absorber was placed outside the laser cavity. The intensity and absorbance of the output beam was observed. From the research, we find that the intensity of laser diode become more decreased with the increase of concentration but not for absorbance. Thus, Rhodamine B have a good performance as a saturable absorber but not suitable for the laser diode.
