well on one of the nasa missions, they set up laser mirrors to guage the distance of the moon accurately, i think they are on the "sea of tranquility".
;D good idea!
apparently thare are mirrors on the moon (man-made of course!) and if you shine a powerfull laser at that part of the moon at the right time and look in a tellescope, you will see it bounce back! MUHAHAHAHA!
LOL! i allmost fell of my perch laughing then!
and that is of course MY collection (looks into the sky in a dreamy manner imagining having such lasers...)
im rather new to lasers and this site and i bet people ask this all the time! but i am making a DVD laser pointer and i am planning on using two AAs to power it (i may decide on it being rechargeable)
i would like the diode to last a long time but also give a fair bit of power!
i was wondering...
