“…(3) The agglomerates are in the form of needles grown in the <111> direction. (4) Immediate surround of luminescent Nd 3+ and Yb 3+ ions is the same in all nanopowders of Y 2 O 3 , independently of the preparation procedure used. Differences in crystallite sizes do not affect luminescent features of nanopowders.…”

Nanopowders of Y 2 O 3 pure, doped and codoped by Nd 3+ , Yb 3+ were obtained by sol-gel method. Solution with ethylene glycol was choosed as the proper solution where crystallites of powder with Nd and Yb dopants had the same size. Finally the one-phased compounds of Y 2 O 3 doped 0.5 at% Nd and 1, 2 or 4 at% Yb were obtained. Grain growth and their morphology were investigated in various temperature and time of heating. The changes of crystallite sizes and lattice constants in relation to the heating time and temperature for the composition Y 2 O 3 doped 0.5 at% Nd and 2 at% Yb are presented. Y 2 O 3 containing 0,5 at% of Nd exhibits intense luminescence bands centered at 920 nm, 1100 nm and 1360 nm whereas a single band at about 1020 nm appears in samples co-doped with neodymium and ytterbium. Luminescence spectra recorded did not depend on the sample preparation procedure and size of grains. OH impurity affects critically the relaxation dynamics of luminescent ion in nanopowders.

“…Moreover sesquioxide Y 2 O 3 can be doped by rare earth ions and it is a good phosphor used in optical displays light emitting devices. Y 2 O 3 was doped by several rare earth, mainly, single ions (Er, Eu, Yb [3,4], Tb, Ho, Nd [5]) and its spectroscopic properties were investigated.…”

“…However, numerous other promising materials for TDLs are currently being investigated in the thin disk geometry [9][10][11][12], in particular materials with broad emission bandwidths for the generation of short pulses [13]. An important example is the family of cubic sesquioxides [14][15][16] ) and supports shorter pulse durations with a larger emission bandwidth (Δλ = 9 nm for Yb:YAG and Δλ = 13 nm for Yb:Lu 2 O 3 ). The excellent properties of this material were confirmed with the demonstration of a modelocked TDL with 141 W and 738-fs pulses [5].…”

Abstract:We present an ultrafast thin disk laser that generates an average output power of 275 W, which is higher than any other modelocked laser oscillator. It is based on the gain material Yb:YAG and operates at a pulse duration of 583 fs and a repetition rate of 16.3 MHz resulting in a pulse energy of 16.9 μJ and a peak power of 25.6 MW. A SESAM designed for high damage threshold initiated and stabilized soliton modelocking. We reduced the nonlinearity of the atmosphere inside the cavity by several orders of magnitude by operating the oscillator in a vacuum environment. Thus soliton modelocking was achieved at moderate amounts of self-phase modulation and negative group delay dispersion. Our approach opens a new avenue for power scaling femtosecond oscillators to the kW level. 435-453 (1996). 19201-19208 (2010). Huber, and U.

“…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.…”

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.
