Force of Helium-Neon Laser

N = Number of photons. P = Power. p = Momentum. h*c = [1240 eV*nm] To find the force the laser exerts on the target, the number of photons per second emitted from the laser must be found. From that, the momentum and then the force can be calculated. First, let’s assume the Helium-Neon laser has a power (P) of 0.8 [mW]. ................
