Patent ID: 7212335

Claim:
An amplification medium performance simulation apparatus for simulating performance of an amplification medium excited by a pump light from a pumping source to amplify a signal light comprising: a basic data retaining unit for retaining basic data of said amplification medium; an input signal light information retaining unit for retaining a total power and a power at each wavelength of an input signal light as information on the input signal light to be inputted to an amplification medium to be simulated; and a simulation executing unit for reckoning a fluctuation in ion population at metastable energy levels corresponding to said input signal wavelength and a wavelength which is specific to said amplification medium, in said amplification medium caused by input of said input signal light, and approximating and calculating an output signal light power at each signal light wavelength outputted from said amplification medium on a basis of a result of the reckoning, by using contents retained in said basic data retaining unit and said input signal light information retaining unit, and outputting a result of the calculation as a result of simulation of the performance of said amplification medium.
