I am looking for a cost effective solution for detecting laser.
Photo transisters are used many times in line following sensors with IR transmitters.
Similarly what can be used for lasers?
please help

LASER is light, therefore any photo transistor or photo diode that has a response to light at the wavelength of the LASER will work.
What is the LASER's wavelength? Red at 660nm? or IR at 890nm? or Green at 550nm?
