Environment Sensing using Femtosecond Laser and it’s modelling for optimising the performance have been discussed in detail in this paper. Femtosecond Fibre Lasers have become very useful for a variety of applications including laser processing, medical bio-optics, opto-electronics., and Environment Sensing. However, to achieve the Optimised performance of the laser system, Modelling of the system is essential. Designing and synthesis of such systems is a complicated technique, since various Mathematical and Characteristics considerations of intensity autocorrelation of output pulses, and the autocorrelation of the compressed pulses have to be taken into account. The purpose of the present paper is to provide the technical analysis of the Modelling and Designing of these systems, after giving a technical description of environmental sensing. In addition, a brief qualitative review of some of the recent important investigations on such laser systems is also discussed. It is hoped that this paper should be really useful for the new researchers, and also for the technologists in the evolving field of environmental sensing field.
