Double Green Laser
Green Laser pointer 30mW. 2AA batteries. could i double the voltage to double the power?
Does anyone know the maximum voltage for a laser diode? or any general suggestions before i try to add more batteries.
i cannot take it apart to mod it, that why i wondering if i could just increase the voltage. to increase the current to increase the power!
It won't work ,coz the power of laser pointer depends on its laser diode not the power supply.

How can a green laser pointer make double burning match?
PHYSICS HELP WOULD BE GREATLY APPRECIATED?
I'm having difficulty with the following problem.
A double slit interference experiment is performed with blue-green argon laser light. The separation between the slits is 0.50mm and the interference pattern on a screen 3.3m away shows the first maximum at a distance of 3.4mm from the centre of the pattern. What is the wavelength of argon laser light?
Thank you so much for your help
n . wavelength = d . x /L
n = 1
d = 5 . 10^–4 m
x = 3.4 . 10^–3 m
L = 3.3 m
Wavelength = 5 . 10^–4 . 3.4 . 10^–3 / 3.4 = 5.56 . 10^–7 m = 556 nm
