An effective gain of 23.8 cm-1 has been got at 1.2×1013 W·cm-2. In this paper, using series codes, quasi-stable Ni-like Ag collisional excitation scheme driven by laser with grazing incidence is studied. Compared with normal incidence, at a drive intensity of 4.3×1013 W·cm-2, the laser energy is mainly deposited on the gain region. The electronic temperature on gain region can be dramatically increased and the gain coefficients can also be dramatically increased. Its effective gain reaches 40 cm-1, which is 3.4 times of that of normal incidence. If 50 J laser energy is used to drive a single target, deeply saturated gain with a gain length product of 40 can be got.
