N2 - Properties of laser radiation and photons are firstly introduced. Planck´s law, Stefan-Boltzmann’s law and Wien´s law are then presented. Spontaneous emission, stimulated absorption, stimulated emission, Einstein coefficients are explained, leading to the definition of important parameters such as laser gain and stimulated emission cross section. Upper level laser rate equation, light increment along an active medium and laser oscillation threshold condition are consequently defined. More importantly, laser rate equation involving a laser resonant cavity is presented, allowing laser photon density calculation within the resonant cavity. Solar concentration ratio, transfer efficiency, absorption efficiency, upper state efficiency, beam overlap efficiency and output coupling efficiency are also explained. A modified analytical method for solar laser power calculation is consequently put forward. Solar laser output power are finally calculated by the modified, classical, Zemax® and LASCAD™ analysis methods.
