In a space mission to Mars, it is needed to equ ip the research robot with a singl e mode l aser to make sample absorbance/transmittance analysis to identify the unkno\vn gases. Assume that all types of lascrs (e.g. gas, solid state, liquid, semiconductor lasers) specified i n the Chapter are offering wavelength ranges and power levels adequate for this application. Which one would you choose for th is application? Specify which properties of this type of laser make it more suitable?
