TL;DR: A compact, low-noise, single-frequency fiber laser by using a newly developed Yb³⁺ heavily doped single-mode phosphate glass fiber has been demonstrated.

TL;DR: This work presents a new pulse-stretching technique, termed free-space angular-chirp-enhanced delay (FACED), with three distinguishing features absent in the prevailing dispersive-fiber-based implementations, and demonstrates not only ultrafast laser-scanning time-stretch imaging with superior bright-field image quality compared with previous work but also, for the first time, MHz fluorescence and colorized time-Stretch microscopy.

TL;DR: In this paper, an asymmetric detection time-stretch optical microscopy (ATOM) was proposed to reveal the enhanced phase-gradient and absorption contrast in microfluidic live-cell imaging at a flow speed as high as 10 m/s, corresponding to an imaging throughput of ~100,000 cells/sec.

TL;DR: To the best of the knowledge, this is the first time that time-stretch imaging could reveal quantitative morphological information of cells and tissues with nanometer precision.

TL;DR: A low noise single-frequency and single-polarization distributed Bragg reflector fiber laser is presented by using a 1.8 cm long newly developed ytterbium-doped phosphate single mode glass fiber.
