Abstract

An ultrafast titanium sapphire (Ti:S) laser equipped with a compact and efficient pump laser is in high demand in many biomedical applications. Recently developed high power visible laser diodes are the cost-effective alternate option to commercial diode-pumped-solid-state lasers for pumping Ti:S. We used two spectrally combined direct laser diodes (LDs) to pump a Ti:S oscillator and demonstrated stable Kerr-lens mode-locking with an average output power of 190 mW. We have carefully studied and realized the beam shaping of both LDs to achieve the maximum pumping efficiency. Furthermore, we have analyzed the noise performance of the overall system.
