The intensity, I, of a light source is given as I- P/A where P is the power of the source and A is the area of the beam. A diode laser with wavelength of 488 nm and power of 10 mW is to be used in a Raman spectroscopy experiment, but you are not sure you will get a large enough intensity to study your sample (at least 3 W/cm is necessary). In order to decide the minimum radius of beam to attain this intensity, produce a plot of the intensity of the beam versus the beam radius. Beam radius can be defined using FHWM or as the distance between the l /e2 points on either side of the Gaussian ( 1/e-13.5% of the value of the beam axis). FWHM = 1.18*(beam radius using 1e2 method). For FWHM values between0.001 to 0.5 cm, construct the plot using 1/e as the measure of beam radius.
