Hey All,
Now that 1W portable lasers are becoming available, it made me wonder how - much higher can it get? I mean the absolute maximum theoretical limit, assuming 100% efficiency in converting battery electricity to light.
Taking for example a portable laser that runs on a 3.7V 2500mAh battery which takes 30 minutes to drain a fully charged battery - what's the limit on its power?
Basically what I'm asking is how do you convert from Volts and milliAmper per hour to Watts? And how would the wavelength affect the numbers? I know there are portable IR lasers with 2.5W output. Can we expect the future to bring us 2.5W 445nm lasers?
Anyone with the physics/engineering knowledge care to explain?
