Abstract

Frequency doubling the 800-850 nm fundamental of Ti:sapphire lasers may make possible pulses of unprecedented short duration in the blue. Both intracavity and extracavity femtosecond pulses from Ti:sapphire and CPM lasers have been demonstrated. Intracavity doubling is more difficult, but it has the advantage of much higher power in the KH₂PO₄ doubling crystal, and therefore, much higher efficiency. To date, the shortest pulses generated using intracavity doubling are 54 fs at 430 nm
