let's consider a DPSS 532nm pointer and a 650nm diode pointer.
to achieve the same dot brightness (not output power!), which pointer will consume the less battery power ? (or current if you prefer)
In theory, you'd need about 14 times the red power (658nm) to equal the brightness of the green. An input of 1W of energy into a green laser yields 100mW (obviously dependent on many parameters) while 1W power input to a red laser diode will give about 350mW. So you'd need 3.8 W input to a red laser to yield the same brightness.
i'm amazed. are you sure that overall efficiency for 532nm generation is 10% which is very good.
so, same question for 405nm:
to achieve the same dot brightness (not output power!), which pointer will consume the less battery power ?
(and if you can same question for beam visibility )
