    I am an 80+ years old ham radio operator (AC8NS) working on a "bucket list" project. Visit optical-eme.groups.io if interested.

    Thank you. I need help with an optics design using a laser diode, such as the Nichia NDG7H75, which emits in multi-transverse modes with wavelengths of 532nm +/-10nm. I want to get rid of the adjacent emission lobes with a spatial filter, expand the remaining TEMoo main lobe to fill a 102mm diameter, 1000mm fl lens and produce a collimated laser beam.:cool:

    You will probably get the best responses to that question in the Optics forum under the Physics area of PF. Start a thread there with links to the datasheet(s) and links to any other useful information that you've run across while working on this project. That should help you to get good responses there. :smile:
