* Single Wavelength: Lasers are designed to emit light of a very specific wavelength. This is what gives laser light its characteristic color and allows it to be focused very precisely.

* Directional: Unlike regular light sources, lasers produce light that travels in a highly collimated beam, meaning it's highly focused and travels in a straight line. This is achieved by carefully aligning the optical components within the laser.

In contrast, regular light sources, like a lightbulb, emit light with a wide range of wavelengths and travel in many directions.
