2025-04-07 Pulse cumulative effect on third harmonic generation from femtosecond laser filament in air doi:10.57760/sciencedb.22151 en This study explores the pulse cumulative effect on third harmonic generation within femtosecond laser filaments in air. By measuring the third harmonic spectrum at different repetition rates, we observe that the spectrum of the third harmonic broadens in the long-wave direction and its intensity increases as the laser repetition rates increases. 飞秒激光成丝; 三次谐波; 重频累计效应; 非线性效应 Yang Chaopeng Wang Tiejun RESTRICTED dataset Science Data Bank
