Abstract:
1. A pumping system for a laser source, said pumping system comprising: at least one pump diode configured to emit at least one pump beam, wherein the wavelength of said pump diode varies with temperature; at least one collimator that receives and collimates said pump beam emitted from said pump diode; and at least one selective mirror for selecting one wavelength of said pump diode, wherein said selective mirror is configured to comprise simultaneously a plurality of spectral reflectivity peaks, having particular separated wavelengths, for locking the operation of said pump diode each time onto at least one of these spectral reflectivity peaks upon a change in temperature of said pump diode so that the pumping system emits a pump beam having a plurality of distinct wavelengths that respectively represent the particular separated wavelengths of the reflectivity peaks, corresponding in succession to a plurality of predetermined wavelengths upon said change in temperature, wherein the pump beam has an extended thermal insensitivity range between at least −40° C. and +70° C.
