dc.description.abstractThe absorption coefficient for ruby‐laser photons in laser‐produced hydrogen plasmas is calculated for temperatures up to 5×105°K using second‐order perturbation theory. The calculations include inverse bremsstrahlung in the field of ions and excited neutral atoms and photoionization. The results are compared to the existing data in literature, which cover the temperature range only below 10 000 °K.en_US
