Target class: tunable laser Context triple: [Ti:sapphire laser, instanceOf, tunable laser]
-
A.
laser
chosen
A laser is a device that emits a focused, coherent beam of light at a specific wavelength through the process of stimulated emission.
-
B.
laser cooling device
A laser cooling device is a system that uses precisely tuned laser light to reduce the kinetic energy of atoms or particles, thereby lowering their temperature to near absolute zero for experimental or technological applications.
-
C.
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.
-
D.
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.
-
E.
gas laser
A gas laser is a type of laser in which an electric current excites a low-pressure gas or gas mixture to produce coherent, monochromatic light through stimulated emission.
- F. None of above.
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.
