In modelocked thin-disk oscillators (Fig. 3-c), a single-transverse mode, high-power laser oscillator is modelocked to generate ultrashort pulses. These systems are very attractive, because they provide energetic pulses at MHz repetition rate from a compact, single oscillator, and they may even give access to increased intra-cavity peak powers.
The thin-disk laser technology allows for lasers with high pulse energy (several hundred mJ to Joule level) and repetition rates of up to the kHz level. A disk with a thickness between several 100 μm and 1 mm is used as the active medium. Compared to laser rods, the cooling efficiency of thin disks is much better, which allows for a higher ...
A solid-state laser system uses a gain medium that is a solid, rather than a liquid, such as in dye laser systems or a gas as in gas laser systems. A disk laser is a type of solid-state laser system that has a heat sink and laser output that are realized on opposite sides of a layer of gain medium.
A disk laser or active mirror (Fig.1) is a type of diode pumped solid-state laser characterized by a heat sink and laser output that are realized on opposite sides of a thin layer of active gain medium . [1] Despite their name, disk lasers do not have to be circular; other shapes have also been tried.

Buyer' guide > Products > thin-disk lasers. Where to Buy Thin-disk Lasers. Thin-disk lasers can produce output powers of many kilowatts in conjunction with excellent beam quality and a high power conversion efficiency, They may emit continuously, but pulse generation restorations between microseconds and femtoseconds is also possible.
The thin-disk laser (sometimes called thin-disc laser or active-mirror laser) is a special kind of diode-pumped high-power solid-state laser, which was introduced in the 1990s by the group of Adolf Giesen at the University of Stuttgart, Germany [2, 18].
The most often used gain medium for thin-disk lasers is Yb:YAG.Compared with Nd:YAG, it has a shorter emission wavelength (typically 1030 nm), a smaller quantum defect (reducing the dissipated power), a longer upper-state lifetime (improving energy storage for Q switching), and a larger gain bandwidth (e.g. for shorter pulses with mode locking).
Therefore, a thin-disk laser resonator can be considered as a resonator containing an internal lens. Thermally induced phase distortions of the field distribution in the resonator can reduce the laser efficiency. Furthermore, th ese aberrations yield a degradation of the beam quality. This aspect is quite irrelevant in multi-mode operation.
In the first part the ideas and the realization of the first thin disk lasers are described. The thin disk laser design and the performance are then discussed in detail. The results for continuous-wave and pulsed operation as well as for amplification of short (ns) and ultra-short (ps, fs) pulses demonstrate the potential of the thin disk laser ...
Thin Disk Modules. Thin Disk Modules (TDM) for guiding the pump light over a thin disk gain media.

Abstract. We report on a thin-disk laser system with more than 10 kW of output power and a beam quality of M 2 = 1.76 at an overall optical-to-optical efficiency of 51%. The system consists of two thin-disk laser oscillators and a thin-disk multi-pass amplifier system. To reach high output powers while maintaining good beam quality, the output ...
Thin-disk technology also has a femtosecond laser on the market. Jenoptik Laser recently introduced its JenLas D2.fs, which the company said opens up new industrial applications for diode-pumped disk lasers due to its 400-fs pulse rate, M 2 beam quality and high pulse energies of 40 μJ at a 100-kHz repetition rate. A booming market
Pulsed lasers. Pulsed laser systems are advantageous for many applications compared to continuous wave (cw) lasers as they allow for generating extremely high radiation intensitie
A thin disk laser is a type of diode-pumped solid-state (DPSS) laser technology in which the gain medium is comprised of a thin disk of typically Yb:YAG crystal. The invention of the thin disk laser came in 1991 through collaboration between the German Aerospace Center and a group at the University of Stuttgart.

Thin disk lasers can be operated in cw-mode as well as in pulsed mode with pulse durations from 100 fs to microseconds. Results from different institutes and companies will be shown demonstrating the power/energy scalability of the thin disk laser design with good beam quality and high efficiency, simultaneously.
The principle design ideas of thin disk lasers will be illustrated and the advantages for operating different laser-active materials will be explained in detail. So far, the maximum laser cw-output power demonstrated from one single disk is more than 10 kW with an optical to optical efficiency of more than 50 %.
