Do laser's output power change in low or high light exposure? Example: I can melt plastic in the dark but in the daylight it is harder. True or false?

The output wont change no. Your subjective opinion might....;)

Edit: Maybe you have trouble, in the day light, seeing the exact focal point to burn?

Well its clear the beam and dot wont be as easy to see and you could easily miss the ideal focal point for burning. Also smoke will be less visible and it wont look as impressive.
The output power is determined by the driver delivering the current and it will not change just because you are using it in daylight! :beer:

The amount of light in the atmosphere has no effect on the lasers power or output, the difference is only visual to the human eye based on how bright it is and what kind of light is present. Outside with sunlight, whatever laser spectrum you're viewing is naturally present in sunlight so algebraically your wavelength is cancelled out depending on how bright & clear it is & how powerful the laser you're using. Inside a lit room it's different depending on what kind of lighting is used (incandescent, florescent, ect) and how bright it is :p

Variables.......
