Due to high conversion efficiency, robustness, easy thermal management and excellent beam quality, single-mode high-power fiber lasers have been developed for a wide variety of applications, such as industry, science and defense. In the past two decades, the large-mode-area (LMA) double-cladding gain fibers and high-brightness semiconductor laser diodes lead to an exponential evolution on the output power of the single-mode fiber lasers. However, the evolution is suffering from a sudden halt due to mode degradation phenomena.

High-intensity lasers provide a unique source of energy and are the key components in a variety of applications, ranging from scientific research to industry and medicine. To reach very high pulse intensities, laser light is typically focused to a small point in space. After focus, the pulse expands and its intensity decreases due to pulse diffraction. However, some applications such as laser wakefield acceleration require laser pulses to remain intense over an extended length. A new development led by Berkeley Lab scientist Marlene Turner expands the reach of this field. The related research results are published on High Power Laser Science and Engineering, Vol.9, Issue 2, 2021 (M. Turner, A. J. Gonsalves, S. S. Bulanov, et al. Radial density profile and stability of capillary discharge plasma waveguides of lengths up to 40 cm[J]. High Power Laser Science and Engineering, 2021, 9(2): 02000e17).

The generation of ultrashort pulses implies a large bandwidth, increasing complexity of the beam propagation, and diagnostics to fully characterize the final pulse in the spatial-temporal domain. The angular dispersion (AD) of the beam is one of the spatial-temporal couplings (STC) playing a key role in a wide range of scientific areas. The presence of this chromatic aberration will distort the laser pulse, causing pulse front tilt. In turn, when the beam is focused, the actual pulse length in the focal spot is different from the pulse length in the near field, where usually is measured.

As an attractive collector medium for hypervelocity particles, combined with outstanding physical properties and suitable compositional characteristics, silica aerogel has been proved as an ideal capture media for space debris, interplanetary dust and shock-loaded fragments (highly transparent, low-density, highly porous, etc.), which can capture the hypervelocity particles efficiently and nondestructively. On the one hand, silica aerogel capture cells had been deployed in space missions and many researches focusing on the captured particles and track had been done. On the other hand, numerous efforts of modeling and experimental approaches were concluded to estimate the conditions of impact in aerogel. Hörz classified the diverse aerogel track shapes into three broad types (A, B, and C), In addition to straight path, track curvature was exhibited at the result of ground experiment in the available reports. The gently curving carrot-shaped -tracks observed in aerogel was assigned as being due to irregular shape of projectile. That is closer to the actual situation that many space debris have irregular shapes. However, till now, there is almost no complete understanding of the impact behaviors and typical track morphology of irregular particles. Thus, it is worthwhile to analyze track morphology of hypervelocity irregular grains in silica aerogel.
