Target class: chirped pulse amplification technique Context triple: [CPA, instanceOf, chirped pulse amplification technique]
-
A.
petawatt-class laser system
A petawatt-class laser system is an ultra-high-power laser capable of delivering peak powers on the order of 10¹⁵ watts in extremely short pulses for advanced research in high-energy-density physics, particle acceleration, and nonlinear optics.
-
B.
Fiber-optic transmission technique
A fiber-optic transmission technique is a method for encoding, sending, and receiving information as light signals through optical fibers to achieve high-speed, low-loss communication over long distances.
-
C.
nonlinear optics phenomenon
A nonlinear optics phenomenon is a process in which the response of a material to intense electromagnetic fields becomes non-proportional to the field strength, leading to effects such as frequency conversion, self-focusing, and harmonic generation.
-
D.
laser
A laser is a device that emits a focused, coherent beam of light at a specific wavelength through the process of stimulated emission.
-
E.
unipolar laser
A unipolar laser is a semiconductor laser device that generates coherent light through electronic transitions within a single type of charge carrier band, typically using intersubband transitions in quantum wells rather than electron–hole recombination.
- F. None of above. chosen
Provenance (1 batch)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
