The author discussed the effect of opacity on stellar evolution and concentrated on the mechanism of triggering blue loop by using Padova stellar model. It shows that extended mixing at the bottom of the convective envelope changed the interior hydrogen profile, which triggers or suppresses blue loop. Laboratory astrophysics, which is a cross subject of astrophysics and plasma physics, combines the demand of accurate data of radiative opacity with the latest advances in high intense lasers to devise the third independent method to study the radiative opacity. On the basis of the comparison between stellar material and laser-produced plasma in terrestrial laboratory, the desirable way to study opacity in laboratory and the brief introduction to the experiments relative to opacity are given.

Based on the conclusion of experimental law, the photoelectric threshold condition is obtained for the semi-insulating GaAs photoconductive switch under the non-linear mode, pointing it out that, when the optic-energy triggers off the switch to meet the prerequisite that n_0L is greater than or equal to 10~(12)cm~(-2), the necessary condition is achieved for high field domain and meanwhile the threshold electric field serves to produce charge transmission effect within the material.
