We report the generation of 26-fs-duration pulses, with an energy of 60 mJ, from a simple multipass Ti:sapphire amplifier system. The peak power of our amplified pulses is 2 TW, and the repetition rate is 10 Hz. Our amplifier design consists of two h

We analyze the performance of a Ti:sapphire self-mode-locked laser with near-zero second- and third-order dispersion. Our simulations show that, in the presence of fourth-order dispersion, solitary laser pulses can be supported within a wide paramete

We have demonstrated the generation of 21 ± 2 fs duration pulses, with an energy of 0.5 mJ, a bandwidth of 44 nm, and a repetition rate of 10 Hz, using a chirped-pulse amplification scheme in Ti:sapphire. We use 11-fs, 5-nJ pulses from a Ti:sapphire

We have generated sub-17-fs-duration pulses directly from a self-mode-locked Ti:sapphire laser. These pulses are near transform limited, with a wavelength centered at 817 nm, a pulse repetition rate of 80 MHz, and an average power of 500 mW. By minim

We show that near-transform-limited 32-fs pulses can be generated directly from a self-mode-locked titanium-doped sapphire oscillator. The laser operates at a center wavelength of 813 nm with a bandwidth of 22 nm in a TEM00 mode. Correct choice of th

In conclusion, we have demonstrated a simple and reliable Ti:sapphire laser amplifier capable of generating pulses of unprecedented short duration. Our results confirm the fact that third-order dispersion is the primary factor limiting pulse duration

Frequency doubling the 800-850 nm fundamental of Ti:sapphire lasers may make possible pulses of unprecedented short duration in the blue. Both intracavity and extracavity femtosecond pulses from Ti:sapphire and CPM lasers have been demonstrated. Intr

We report on a Ti:sapphire amplifier system which produces 21 fs, 1 mJ pulses at 1 kHz. A nanojoule-level seed pulse makes 8 passes through a highly doped Ti:sapphire crystal for a total gain of approximately 106. The crystal is pumped with 12 mJ of
