In this talk we first review the historical development of commercial mode-locked lasers based on titanium doped sapphire, including experimental and theoretical data highlighting the limits of these lasers, especially average output power and tuning range. Commercially available one-box systems are rapidly approaching these limits, with the latest systems offering an average power of more than 2.9W at 800nm, corresponding to more than 350kW peak power. In addition, systems are now becoming available with an extremely wide tuning range, extending from just under 700nm to over 1020nm, using only a single set of optics. These achievements enable further advancements of applications, such as micromachining, which require the highest peak power with increased throughput rates, and multi-photon microscopy where increased tunability and higher average power are of particular benefit. Some of the remaining challenges and the innovative techniques used to address them will also be discussed during the presentation.
In this talk we will present an overview of recent development of ultrafast lasers sources and their applications. This talk
will highlight some recent state of the art ultrafast pulse results from Ti:Sapphire and Ytterbium based laser systems.
There are significant advantages in being able to directly diode pump Ytterbium materials resulting in more compact
bulk solid state and fiber based laser systems. Several newly emerging technologies such as Optical Parametric Chirped
Pulse Amplification, and Supercontinuum Generation have generated great excitement in recent years. The evolution of
more compact and user friendly ultrafast laser systems has enabled completely new fields that take advantage of the
extremely high peak powers and very short time duration of ultrafast laser pulses. Recent results in the fields of
multiphoton microscopy, micromachining, 3-D fabrication, and spectroscopy will be discussed.
