Hi,
I have spent the last two days reading this wonderful forum. I am hoping that the knowledgeable experts here will have time to answer my question.
Here goes.... Imagine that I need to signal a craft orbiting the Earth as I stand near a major city at night.

Can someone give me some insight on best wavelength (blue, green, etc.) and how much power I will need. It would be best if the laser was a hand-held style so I can be mobile and move to different areas.
Thank you very much!
