    Abstract

    According to the mode-locked femt second Ti∶sapphire laser pulse compression, the characteristics and principles of dispersion compensation of negative dispersion mirrors were introduced. Optimized Gires-Touronis (OG-T) mirrors were designed and fabricated. OG-T mirrors were deposited by means of ion-beam sputtering onto superpolished substrates. The transmittance and group dispersion delay of first fabricated OG-T (OGT#1) mirrors were measured. Film coating parameters were adjusted according with design value. After that, second fabricated OG-T (OGT#2) mirrors were fabricated. Dispersion was compensated by 5 bounces during 3 OG-T mirrors from mode-locked femtosecond Ti∶sapphire laser. 32 fs pulse (46 nm spectrum width) and 15 fs pulse (91 nm spectrum width) were obtained respectively by OGT#1 and OGT#2. The excellent features of negative dispersion mirrors were proved by the experiment and the fine chirped mirrors could be fabricated.
