Dear John,

I agree that the method will produce empirical results. However, there are a few questions I have in reference to the laser setup and adjustment.  But we can discuss that at a later time if you wish.

Good Evening Mike

Thank you for your reply.

This is a completely transparent process, so please, let’s discuss the laser set-up and adjustment now.

Look forward to hearing from you

Kind Regards

John

Ok. 1st question

30000 mw seems unlikely as output power of the laser. 30 watts will burn holes in anything with a close proximity.  Can you verify that is the actual output power? And how will the lasers be powered?

Hi Mike

Here is the website:

It is probably less than is stated….  Have I got that wrong?  Your thoughts

Kind regards

To give a little contrast. Our specially designed collimated laser had and output power of 3watts and costs 4000 euros.

30 watts will burn your cap with hole into a melting blob.

The general rule of thumb with these laser pointers is you divide the output power by 5 to get the actual figure and in the case of made in China that is a factor of 10.

And I also notice they are battery powered which limits their use time. Ours lasted about 10 minutes until it faded out completely. That is a small window to target and document it. The other issue I see is the intensity loss due to the cap with hole. It will cut off the outer edges of the beam leaving a slight decreased intensity and I’m not sure if that will impact visibility.

The adjustment of the apparatus is done manually?

Hi Mike

The lasers work for about 30 – 45 minutes and we have spare batteries.

The P1000 does an amazing job – pictures from the trial run – 15 km away:
