For a 660nm laser, Assuming a silicon diode is 0.7V and you need 4 of them for 660nm Lasers, 4x 0.7 = 2.8V.
So if I apply 3.35V’s (2.8 + 0.550) to the diode I would get 550mA of current.
So power going into the LD would = 3.35V x 0.550A = 1.8425W’s
Does that look right?
Now my Optical Output for this laser is 384mW’s.
Now to calculate the efficiency of the energy conversion.
Output/Input x 100 = Efficiency
0.384 / 1.8425 x 100 = 20.84%
Some feedback would be nice
Cheers!
