Hi Everyone!
Let's say I expand a laser diode (single mode or multi-mode) using a set of cylindrical lenses, and measure the resulting illumination pattern using a camera. Will the illumination pattern that I image vary:
1) From diode to diode?
2) Depending on the temperature of the diode?
3) Depending on the output power of the diode? (Obviously the absolute intensity will increase, but will the pattern change?)
4) Depending on the age of the diode (e.g. wear and tear)?
5) Depending on the time that the diode is on?
6) Any other factors that might affect the illumination pattern?
Looking for either experimental data or a physics explanation. Thanks!
