Default Laser Light Properties

Hi,
Im trying to understand how to work out the luminance or luminance intensity a laser diode can emit. Most of the maths I've seen when looking around is full of variables I don't understand. Is there a simple way to work out the properties of the light produced using the wavelength, output power, spot size, etc?

Thanks

Hi.

I posted this in another thread some time ago... The information may or may not be accurate, but it is the best I could find.

Quote:
... you can check this table for the Luminous efficacy at whatever wavelength laser you are using:
Luminous Efficacy
Both photopic (light adapted eyes) and scotopic (dark adapted eyes) conversions are listed.

To calculate approximately how many lumens your laser is outputting, take the lm/W value for your specific wavelength and multiply it by the power of your laser in Watts.
Again, for my PGL:
Photopic: 588.746 * 0.65W = 382.6849 lm
Scotopic: 1378.7 * 0.65W= 896.155 lm

I'm not sure how accurate this Watt to Lumen vs. Wavelength conversion is but it seems about right.
This is the thread:
