In reference to the specifications of a laser diode below:
I wish to be able to model it as a gaussian laser beam. I understand there is a formula (see below)
where if I know the wavelength and the divergence angle I can work out the waist size. The laser diode specifications give me a divergence angle, but where on the actual laser diode is the waist located? Is it right on the diode surface? Is the waist location the same for both the fast and slow axis?
