“…In 2002, a modelocked TDL based on this material was presented with an average power of 22 W and a pulse duration of 240 fs [66]. In this result, these short pulse durations were achieved with an intracavity prism in order to tune-off the narrow maximum emission peak thus broadening and flattening the emission spectrum.…”

A growing number of applications in science and industry are currently pushing the development of ultrafast laser technologies that enable high average powers. SESAM modelocked thin disk lasers (TDLs) currently achieve higher pulse energies and average powers than any other ultrafast oscillator technology, making them excellent candidates in this goal. Recently, 275 W of average power with a pulse duration of 583 fs were demonstrated, which represents the highest average power so far demonstrated from an ultrafast oscillator. In terms of pulse energy, TDLs reach more than 40 μJ pulses directly from the oscillator. In addition, another major milestone was recently achieved, with the demonstration of a TDL with nearly bandwidth-limited 96-fs long pulses. The progress achieved in terms of pulse duration of such sources enabled the first measurement of the carrier-envelope offset frequency of a modelocked TDL, which is the first key step towards full stabilization of such a source. We will present the key elements that enabled these latest results, as well as an outlook towards the next scaling steps in average power, pulse OPEN ACCESSAppl. Sci. 2013, 3 356 energy and pulse duration of such sources. These cutting-edge sources will enable exciting new applications, and open the door to further extending the current performance milestones.

“…A sister material, Yb:KYW, was also used for ultrashort pulse generation, yielding pulses as short as 71 fs [12]. When applied to a more sophisticated thin-disk geometry, the Yb:KYW oscillator produced 22W of average power in 240 fs duration pulses [13].…”

We report on the development of diode-pumped high power continuous-wave (CW) and ultrashort pulse Yb:KGW lasers for applications in nonlinear multimodal microscopy. In the CW regime we generated 5W of average output power from a simple three-mirror cavity, with 22% of optical-to-optical conversion efficiency. The CW laser was used as a platform for development of a high power mode-locked oscillator. We achieved 2.3W of average output power in the mode-locked regime with ~210 fs duration pulses centered around 1047 nm at a repetition rate of 97 MHz. This corresponds to 24 nJ of energy per pulse and 114 kW of peak power. The demonstrated laser will be used in second-and third-harmonic generation microscopy of biological samples.

“…High power diode bars with 50% electrical-to-light efficiency are commercially available [7], with further improvement possible. Lasing media with 86.9% slope efficiencies (Yb:KY(WO 4 ) 2 [8], λ=1.025 µm) have already been used to make high average power lasers achieving better than 10% wall-plug-to-light efficiencies [9], with limiting efficiencies approaching 40% possible.…”

Recent technological progress in lasers has renewed interest in applying high power lasers to accelerate charged particles. Outstanding gains in efficiency and power, and the first demonstration of optical phase-locking have moved the laser closer to competitive standing with microwave vacuum tubes as power sources for accelerators. We explore some of the questions that will determine the suitability of both low-field (a o «1) and high-field (a o >1) acceleration methods, and identify some of the challenges ahead. Possible applications include a laser-driven linear collider and novel, compact particle and radiation sources, each with its own performance requirements.
