CEO/CEP stabilisation of Ti:sapphire femtosecond lasers without AOM

The carrier-envelope offset frequency and phase of a Ti:sapphire femtosecond laser can be stabilized by directly feeding back to the output power of a 532 nm finesse pure 10 Watt pump laser with CEP feature.

The performance with this approach matches that of traditional setups employing acousto-optic modulators in the pump beam (~100 mrad integrated phase noise) but has potential for massive improvement due to the enhanced available modulation bandwidth compared to AOMs (approximately 700 kHz versus tens of kHz).
