Generation of 10 fs Ti:sapphire laser at repetition rate of 525 MHz and measurement of carrier-envelope phase frequency
2009年
This paper presents a Kerr-lens mode-locked Ti:sapphire laser at the repetition rate of 525 MHz, stable laser pulse as short as 10 fs with average output power of 480 mW is obtained. By injecting the pulse into photonics crystal fibre, octave-spanning spectrum covered from 500 to 1050 nm is generated, carrier-envelope phase frequency with signal-to- noise ratio of 31dB is measured, which paves the way for the generation of a compact frequency comb.

Sub-10 fs laser pulses with repetition rate of 1.1 GHz by a Ti:sapphire oscillator被引量:3
2009年
We demonstrate a compact Ti:sapphire oscillator with ring cavity configuration.By optimizing the intra-cavity dispersion with chirped mirrors,pulses with repetition rate of 1.1 GHz are coupled out by the uncoated wedges in the cavity.Under 7W CW pump laser centered at 532 nm,the average power of the output pulses is about 30 mW,the duration is less than 10fs and the spectrum spans from 670 nm to 920 nm.
