Material-structure-performance integrated laser-metal additive manufacturing
Science, 2021Cross-scale coordination Laser-based additive manufacturing has the potential to revolutionize how components are designed. Gu et al. suggest moving away from a strategy that designs and builds components in a serial manner for a more wholistic method of

Optics News, 1984
The soliton laser1 is a novel mode-locked device employing a length of single mode fiber in its feedback loop. Its pulse width can be made to have any desired value, down to a small fraction of a picosecond, through choice of the fiber’s length. Operation is based on the ability of single mode fibers, in the region (λ> 1.3 µm) of negative group ...

Choice of lasers for laser angioplasty
Journal of Tongji Medical University, 1989Thrombi in test-tube, intraarterial thrombi and pig aorta wall were in vitro irradiated with continuous CO2 laser, short pulsal and ultrashort pulsal YAG laser (with pulse-width of 10 ns and 40 ps, respectively) and their double frequency laser and excimer laser with a wave-length of 308 nm and pulse-width of 20 ns.

Massively parallel coherent laser ranging using a soliton microcomb
Nature, 2019Coherent ranging, also known as frequency-modulated continuous-wave (FMCW) laser-based light detection and ranging (lidar)1 is used for long-range three-dimensional distance and velocimetry in autonomous driving2,3. FMCW lidar maps distance to frequency4,

Survey Review, 1974
Abstract Because lasers are being used increasingly in surveying, knowledge of the way in which a laser beam can damage the human eye is essential. This article describes the process by which damage to the retina may occur, and examines some methods by which this hazard can be reduced, if not eliminated.
