A laser is coherent light. Virtually all the photons have the same wavelength and can be superimposed. A flashlight is "white light". The red, blue, green, ect. wavelengths don't fall easily together (trough on trough and crest on crest).

When dealing with one photon at a time through a slit aperture you couldn't tell if the photon source was a laser or light bulb.
