Are there photocells that are sensitive to laser light only?

Answer:
No. Light is light.

A:
It's the wavelength that photodiodes are sensitive too. Specs vary widely, so photo emmitters have to be matched with photodiodes, or they won't 'see the light' This comes in handy when using your IR remote on a fairly bright day. If your TV could see all light, it would be blinded.
