Figureshows the Gain as a function of Amplifying Material Length (Tm - doped material) for three incident input pulse energies, e.g. 4mJ, 6mJ and 8mJ at wavelength near 2 um using 790 nm pump light. The similar type of simulations can be done for Ho - dopedor any combinations of Ho - Tm co-doped or other Rare Earth co-doped materials for input pulses of arbitrary widths (down to femtoseconds), arbitrary repetition rates and arbitrary energy levels. |
Figureshows the electron population densities of ground state at the sample input surface (blue line) and at the mid‐point of the amplifier material (orange line) during the time that the pump pulse is passing through the sample. At the sample input surface, the population of the ground state is nearly depleted by the pump beam, which can affect the amplification efficiency as once the ground state is depleted of ions, the state will no longer absorb the pump light. |
