As a member of the Townes Laser Institute, the Laser Plasma Laboratory (LPL) has invested in thin disk lasers as part of advanced laser development efforts. In 2010 LPL began an active partnership with Trumpf , the leading manufacturer of thin disk laser systems. We currently have a joint program to develop high-energy pulsed laser systems ...
The 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.
Abstract This paper investigates the general limitations of thin-disk laser (TDL) resonators due to the dioptric power variation of thin-disk (TD) crystal to attain the good beam quality. For this reason, the generalized formulation of TDL resonator in geometric optics theory is analytically derived. The analytical model is developed by considering two general configurations of stable ...

The thin-disk laser is a diode-pumped solid-state laser that produces high output power with both high efficiency and excellent beam quality. Since the first demonstration of the principle, by Adolf Giesen at the University of Stuttgart in 1993, 1 the continuous-wave output power extracted from a single disk has increased to more than 5 kW.
Thin-disk laser. A thin-disc laser is a type of solid-state laser, whereas the active medium (laser crystal) has the shape of a disk. The heat sink and the laser output are realized on opposite sides of the active medium. The thickness of the laser disk is usually between 80 µm and 200 µm. The back is steamed with an high-reflectively coating.
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.
We present the first demonstration of a thin-disk laser based on the gain material Yb:GGG. This material has many desirable properties for the thin-disk geometry: a high thermal conductivity, which is nearly independent of the doping concentration, a low quantum defect, low-temperature growth, and a broadband absorption spectrum, making it a promising contender to the well-established Yb:YAG ...
The thin disc laser is presented as an optimal laser design for the operation of a quasi-three-level laser active medium in the high power regime with high optical efficiency. Numerical calculations of the laser output power show that operation with an output power up to 1 kW with an optical efficiency of 50% and more is possible at room temperature utilizing 16 absorption passes. Scaling of ...
Before the thin disk laser, one of the first improvements started as a thin slab laser utilizing both sides of the gain medium pumped with light. This design
Based on quasi-three-level system, a numerical model of continuous wave thin disc laser is proposed. The fluorescence concentration quenching (FCQ), refractive index depending concentration effects and temperature distribution in the gain medium have been taken into account in the model.
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 thickness of one of these disks (typically 150µm to 200µm thick) is substantially smaller than the beam diameter.
high power thin disk laser, whereas fi-ber lasers in contrast require an order of magnitude higher brilliance. In the 6 kW/disk cw laser generation, a fur-ther optimized pump cavity boosts the optical efficiency to greater than 72 %, a 10 % increase compared to the previous generation.

During the early 1990s, collaboration between the German Aerospace Center and the University of Stuttgart started to work on the Thin Disk concept. The core idea behind the thin disk design is the use of a thin, disk-shaped active medium that is cooled through one of the flat faces of the disk. This ensures a large surface-to-volume ratio and therefore provides very efficient thermal ...

Several measurement techniques were performed on a high power thin disk laser. The system e ciencies, spectrum, and temporal characteristics were examined. The laser was characterized in the far- eld regime to determine the beam quality and intensity of the laser. Laser cavity simulations of the thin disk laser were performed using LASCAD. The
Using this metrology tool allows one to achieve sub- micron control over the thickness of an entire polishing block of YAG. While most thin disk laser designs do not require a thickness tolerance any less than ~5 microns, more precise metrology tools can be very useful in checking the wedge across a single YAG disk.
Thin-disk laser design and performance are then discussed in detail. Results for continuous-wave and pulsed operation as well as for amplification of short (nanosecond) and ultra-short (picosecond, femtosecond) pulses demonstrate the potential of thin-disk laser design.
The scaling laws for this laser design show that the power limit for CW operation is far beyond 40 kW for one single disk and the energy limit is higher than 3 J from one disk in pulsed operation. Also, the applicability of the thin-disk laser concept to optically pumped semiconductor structures will be discussed.
This paper investigates the general limitations of thin-disk laser (TDL) resonators due to the dioptric power variation of thin-disk (TD) crystal to attain the good beam quality. For this reason, the generalized formulation of TDL resonator in geometric optics theory is analytically derived.
