详细
The transmission of high-power HF(DF) laser radiation through Ge single crystals of different quality has been experimentally and numerically investigated. Based on the experimental data for the lasing spectrum, the two-photon absorption coefficient in Ge is estimated to be K2 =55±10 cmGW−1 at λ=2.8μm. The transmission dynamics of high-power radiation with λ=2.6−3 μm through germanium crystals is numerically simulated.
