| Abstract | |
This work presents a compact sub-100-fs, low-energy Kerr-lens modelocked Ti:Sapphire bulk laser oscillator operating at a 1-GHz repetition rate. The laser features a bow-tie cavity using dispersion-compensating mirrors and operates in a modelocked regime, achieving an average power of 0.94 W at 7.4 W of pump power. It produces a broadband emission of 31 nm centered at 756 nm, with low-energy pulses of 1 nJ, a temporal width of 61 fs, and a peak power of 15 kW. The compact laser setup shows great potential for various applications in spectroscopy and metrology. (AU) | |
