Abstract :
The goal of this research is to characterize different biological cells with the help of intracavity spectroscopy following the work of Gourley et al in 1997. This paper reports initial results on device fabrication, and modulation of laser threshold and slope efficiency, with the bioanalyte´s refractive index. An approximate mathematical model is also proposed to support the experimental results.
