✔️✔️${\mathbb{CORRECT... ANSWER}}$✔️✔️

✔️✔️ For specificity let's assume the laser diode is operating at 532 nm and the pattern is a regular, 40 x 40 pattern of 'dots' covering a 30 degree by 30 degree field.


Suppose now that I swap out the single mode laser source for a higher power multimode laser diode source operating at the same wavelength of 532 nm.

Assuming I take the requisite amount of care to make sure things align correctly and so on, what would you expect the effect of this swap to be on the generated pattern.

Answer 2

Heya...

See your answer here !

==============

For specify let's assume the laser lode is operating at 532 NM and the pattern is regular 40*40 with covering same field of 30° ..>

Suppose if I swap out for higher power multimodal assume wavelength that is 532 NM ...

It's take the amount to matter sure thing to care the align on your experienced effect on generated pattern.

Thank you
