Image of the Week: Stem Autofluorescence

Autofluorescence image of an avocado (Persea americana) stem cross-section. The intrinsic fluorescence highlights the structural organization of vascular tissues, with xylem vessels and surrounding cell walls clearly delineated in bright green. Autofluorescence signal arises primarily from lignin and phenolic compounds in secondary cell walls.

In a recent study, Cornell University researchers demonstrate the single-mode nonlinear amplification of femtosecond pulses in a multimode-fiber regenerative amplifier https://bit.ly/432Wrze

By optimizing the seed pulse duration, the team achieved pulse energies up to 10 μJ with good beam quality, subsequently compressed to w 98 fs duration. Factors that limit the performance of this amplifier are also discussed.

Scientists made an opaque material transparent by combining light shaping and quantum entanglement.

Hugo Defienne, the work's principal investigator, said: "What we have shown is that when we take entangled particles, that is, pairs of entangled photons, thanks to light shaping, we can ultimately maintain the relative angle between these particles."

By filtering out background noise and retaining only quantum info, entanglement acts as a shield against interference for quantum telecommunications.
