Titanium-doped sapphire (Ti:sapphire) lasers have enabled major advances over the past decades, from optical frequency combs to multiphoton microscopy. Their unmatched bandwidth and tunability make them indispensable for applications in atomic physics and quantum optics. However, their widespread use remains limited by system size, cost, and high optical pump requirements. In this presentation, I will introduce our work on monocrystalline Ti:sapphire-on-insulator (Ti:SaOI) photonics, which enables chip-scale integration of Ti:sapphire gain for compact, scalable, and high-performance laser systems.
