How this entity was disambiguated
This entity first appeared as the object of triple T11665261 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: Ti:sapphire lasers Context triple: [chirped pulse amplification, relatedTo, Ti:sapphire lasers]
-
A.
helium–neon laser
The helium–neon laser is a type of gas laser, commonly emitting visible red light at 632.8 nm, widely used for alignment, holography, and educational demonstrations due to its stable, low-power coherent beam.
-
B.
Lasers
Lasers is Lupe Fiasco’s third studio album, known for its politically charged lyrics, pop-oriented production, and contentious relationship with both his label and core fanbase.
-
C.
erbium-doped fiber amplifier
An erbium-doped fiber amplifier is an optical device that boosts the strength of light signals in fiber-optic communication systems by using erbium ions in the fiber core to provide efficient, low-noise signal amplification.
-
D.
Spectral Band Replication
Spectral Band Replication is an audio coding enhancement technique that reconstructs high-frequency components from lower-frequency data to improve compression efficiency at low bitrates.
-
E.
chirped pulse amplification
Chirped pulse amplification is a laser technique that stretches, amplifies, and then recompresses ultrashort light pulses to achieve extremely high peak powers without damaging optical components.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
