“…It displays a monotonic decrease in k as temperature is lowered, as expected due to a locally disordered crystal structure that severely limits the phonon mean free path. In Figure 17 the thermal conductivity values for the GdVO 4 c and a axes, the YSO b-axis, and for GSAG are shown as a function of absolute temperature [3,30]. .…”

Ultrafast laser physics continues to advance at a rapid pace, driven primarily by the development of more powerful and sophisticated diode-pumping sources, the development of new laser materials, and new laser and amplification approaches such as optical parametric chirped-pulse amplification. The rapid development of high average power cryogenic laser sources seems likely to play a crucial role in realizing the long-sought goal of powerful ultrafast sources that offer concomitant high peak and average powers. In this paper, we review the optical, thermal, thermo-optic and laser parameters important to cryogenic laser technology, recently achieved laser and laser materials progress, the progression of cryogenic laser technology, discuss the importance of cryogenic laser technology in ultrafast laser science, and what advances are likely to be achieved in the near-future.

“…The pulse build-up evolution in the cavity of the regenerative amplifier is shown in Figure 7a. The pulse build-up evolution is not fully saturated due to the low gain per roundtrip of about 1.15 for the maximum output, which corresponds to the total gain of about 2.4 × 10 5 . The dependence of the uncompressed output pulse power and the optical-to-optical conversion efficiency on the pump power is shown in Figure 7b.…”

“…Compared to the Nd:YAG, the Yb:YAG has a lower quantum defect and broader emission bandwidth, allowing for the generation of picosecond or even femtosecond pulses. The other Yb-doped materials used in lasers are, e.g., Yb:LuAG (lutetium aluminum garnet), Yb:YLF (yttrium lithium fluoride), Yb:CaF2 (calcium fluoride), Yb:KYW (potassium yttrium tungstate), Yb:KGW (potassium gadolinium tungstate), Yb:CALGO (Yb:CaAlGdO4) and Yb:glass, especially in the form of optical fibers [3][4][5][6][7].…”

An overview of the latest developments of kilowatt-level diode pumped solid state lasers for advanced applications at the HiLASE Centre is presented. An overview of subcontracted and in-house-developed laser beamlines is presented. The aim of development is to build kW-class beamlines delivering picosecond pulses between 1-and 100-kHz repetition rates and high-energy nanosecond pulses at 10 Hz. The picosecond beamlines are based on Yb:YAG thin-disk amplifiers and chirped pulse amplification. The current status of the beamlines' performance is reported. The advantages of zero-phonon line and pulsed OPEN ACCESS Appl. Sci. 2015, 5638 pumping are demonstrated with respect to efficiency, thin disk temperature and beam quality. New diagnostics methods supporting the high average power lasers' development, such as the high-resolution spectroscopy of Yb-doped materials, in situ thin disk deformation measurements, single-shot M 2 measurement, realization of wavefront correction by a deformable mirror and the laser performance of a new mixed garnet ceramics, are described. The energetic, thermal and fluid-mechanical numerical modeling for the optimization of the multi-slab amplifiers is also described.
