>Thee miiiiight be some merit to some as a blinding weapon.
This is sort of a double edged sword.
First, it's use on any battlefield with any quantity, regularity will draw immediate, justified vilification by most reasonable people.
It's cruel to permanently deprive someone of their sight on purpose, regardless of the situation. Battlefield ethics is a grey area for sure, but this pushes boundaries beyond what most are comfortable with. When you employ this as a tactic, you're not looking to kill with a potential side effect of wounding, you're looking to wound and permanently disable, with no chance of killing.
You use this, it will be a black mark and stain on your reputation forever.
Second, it can just as easily be used against you.
This is not some farfetched tech that really needs development - most Blu-ray players have an ultraviolet diode capable of causing retinal damage from ~30 feet away pretty easily - most motivated individuals with basic electronics tech education could design a simple version and put one together in a day provided all the material was available.
If you use them on your enemies, it's immediately justification for them to do the same to you in turn.
Third, and probably why it's mainly not considered realistically more often, it's sort of simple to defeat.
Most man portable lasers capable of blinding can be stopped with goggles.
If you employ a fixed position for the purpose, you create an immediate, ultra right target anyone with an IR seeking weapon can take out immediately.
