To encap: Great information, especially the ophir 'pointer' [no pun intended]. :) Ophir -- very useful specialized camera -- so far seems to be exactly what I need.

Cameras don't seem to be good at detecting laser-spots/reflections in their view-finder. It ends up showing just as a spot, about the same as a big tree-leaf on the ground. The human eye sees the intense reflection like INSANE/RIDICULOUS, but NOT the camera. (In fact even the sun, which you...

really?

typo -- sorry.

Anyone know of a yellow laser (and vendor source) that would be similar to this 0.8watt 532nm dpss 10X one at 0.4 miles, similar in terms of strength/brightness and beam-diameter: https://www.jetlasers.org/index.php?id_product=10&controller=product

Anyone know of a red laser (and vendor source) that would be similar to this 0.8watt 532nm dpss 10X one at 0.4 miles, similar in terms of strength/brightness and beam-diameter: https://www.jetlasers.org/index.php?id_product=10&controller=product

Great thanks. I didn't know the first knob could be adjusted completely independent of the 2nd knob (in the way you described). Will try that on one of mine that needs tightening-up of the beam.

That's a great answer. I was kinda wondering if there is a very-systematic way to do it. It's a two-dimensional search (two knobs), which could seemingly take a long time without some systematic method. (If there were only one knob, it would be cakewalk, of course.)

I know this will end up being a dumb question, but when you buy a laser from jetlasers.org, what is the best way to dial/tune the two knobs to make the beam as small as possible at large distances (half a mile, e.g.)? There are two knobs when you buy a laser with a 10x expander. [My first...

Does anyone know a rough estimate of the end-cost ($) of a 1kilowatt (1kW) infrared (say 1000nm) laser with a beam-diameter of about 6inches at 0.4 miles? (I am guessing the cost will be pretty ridiculous; but, I thought it wouldn't hurt to ask.) Also, what would the weight be roughly?

At this juncture, I think that you and Immo1282 are correct that it is a mirage-type-effect.

The car engine was running. But, there is quite a long extension cord from the inverter to the laser. The laser itself should be pretty steady. You can see its reflection-center-point is not moving, in the 2nd clip. I can drop the voltage myself, but at the moment it was a quick way to be...

Is there a way to stop a DPSS 532nm laser (0.9watt) from flickering as in the attached short clip? It is about a 5Hz flicker of significant intensity-magnitude. Full-disclosure -- it is running off of an 5volt-adapter connected to a power-inverter which is connected to a 12volt car battery...

A $700 laser has a hole in it?

It is a project, whose details cannot be stated. I am not a terrorist. lol. (I assume "stock" meant "stalk"). It is true I am very new to lasers. So, some dumb-questions are partially inevitable. Just ignore my posts if you don't want to 'babysit'.
