“…Earlier attempts with the Verneuil-method [9], the floating zone technique [10], the laser-heated pedestal growth (LPHG) [11], and very recently the growth of Tm:Y 2 O 3 by the micro-pullingdown technique [12] resulted in crystals limited in size and quality. Another promising alternative for the preparation of sesquioxides is the fabrication of ceramic laser materials, which has been studied intensely [13][14][15].…”

“…This family has been recognized as potentially suitable to outperform Yb:YAG in terms of efficiency and shorter pulse durations [93][94][95][96][97][98][99]. These isotropic materials combine high mechanical strength, excellent thermal properties and high absorption cross sections.…”

“…These isotropic materials combine high mechanical strength, excellent thermal properties and high absorption cross sections. Although these cubic sesquioxide materials are known since 1957 [97], the high melting temperature of about 2400 °C has limited the growth of high quality large crystals suitable TDL operation. This resulted for many years in a poor crystal quality and moderate optical-to-optical efficiencies [100,101].…”

Cutting-Edge High-Power Ultrafast Thin Disk Oscillators

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.

“…In the past, growth of Y 2 O 3 , Sc 2 O 3 , and Lu 2 O 3 single crystals was performed by various methods such as CZ [1], Heat Exchanger Method (HEM) [2,3], Bridgman method [4], Laser Heated Pedestal Growth (LHPG) [5,6], Verneuil process [7], Floating Zone method (FZ) [8], and flux growth [9]. Recently, growth of these crystals by the micro-pulling-down (m-PD) method was also demonstrated [10][11][12][13].…”
