On the compression of a thin disk
International Journal of Mechanical Sciences, 1965Abstract A solution is obtained for high-speed compression of a visco-plastic disk between smooth dies. Also an extension of Siebel's procedure for considering plastic compression of a disk between “slightly” rough dies is presented. The relative importance of viscous and inertia effects for various rates of compression of disks of pure lead is ...

Electromagnetic response of thin disks
ZAMP Zeitschrift f�r angewandte Mathematik und Physik, 1988The electromagnetic response of a thin disk with finite conductivity in free space to an arbitrary sinusoidal primary magnetic field is solved through use of an orthogonal expansion in Bessel functions. The eddy currents induced in the disk and the secondary magnetic field are calculated for various locations of a dipole generating the primary field ...

CLEO: 2014, 2014
Short-pulse-pumped optical parametric chirped pulse amplification (OPCPA) demands powerful picosecond lasers with high average powers and high pulse energies. We report on the current picosecond thin-disk amplifiers development and their applications in research.

The chapter reviews the Novikov-Thorne model, which is the standard framework for geometrically thin and optically thick accretion disks around black holes, pointing out its assumptions. It also describes the transfer function for thin accretion disks and how the transfer function can be calculated in a stationary and axisymmetric spacetime and in the ...

Scaling of thin disk pulse amplifiers
SPIE Proceedings, 2008In the past decade, the Thin Disk laser design was very successful as a high power laser design for cw lasers with good beam quality and high efficiency. Several numerical models show that the actually demonstrated output powers are far below the scaling limits due to amplified spontaneous emission (ASE).

Thin interpolating sequences in the disk
Archiv der Mathematik, 2009Using a kind of summability procedure we give, within this survey, a new proof of a result by Sundberg and Wolff on large perturbations of thin interpolating sequences and present a detailed proof of the statement of Dyakonov and Nicolau that asymptotic interpolation problems in H∞ can be solved by thin Blaschke products.

Journal of Geophysical Research: Space Physics, 1983
The MHD equilibrium of thin, rotating plasma disks is considered. An axisymmetric steady state is assumed. A corotation lag is included, as is a nonzero toroidal field with Bф ∝ rBr. Rigorous expressions are obtained for a characteristic Alfvén Mach number and temperature, both of which involve vertical averages.

Thin-disk laser technology [1, 2] combines the inherent advantages of allowing extremely high average power, excellent beam quality, and high peak power levels [3]. In this chapter the benefits and limitations of the thin-disk concept with respect to ultrafast operation will be discussed.

Thin disk laser—Energy scaling
Laser Physics, 2009A time resolved numerical model of the interaction between pump absorption, excitation and amplified spontaneous emission (ASE) for the Thin Disk laser design was developed. The model accounts for the spectral distribution of the spontaneous emission, the spectral and spatial distribution of emission and absorption and the spectral and angular ...
