Chronic Pain 655 nm at 1500mw
415 nm at 1527mw the fiber area that means 1.5mm diameter (0.15cm) Area = 3.14 x ( 0.15 / 2 )^2 = 0.0177 cm^2 Irradiance = 27 mW / 0.0177 cm^2 = 1527 mW/cm^2 = 1.5 W/cm^2
In case you are holding the fiber tip 1cm above tissue due to NA you have spot of ~1cm diameter Area = 3.14 x ( 1/ 2 )^2 = 0.785 cm^2 Irradiance = 27 mW / 0.785 cm^2 = 34.4 mW/cm^2
