    Is there a way to stop a DPSS 532nm laser (0.9watt) from flickering as in the attached short clip?

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

    Is there a way to stop a DPSS 532nm laser (0.9watt) from flickering as in the attached short clip?

    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?

    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...

    Jetlasers PL-e PRO 800mw@532nm "Boomstick" Review

    A $700 laser has a hole in it?

    Looking for a laser for 600yard application.

    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'.

    Looking for a laser for 600yard application.

    Ok, Encap, I didn't read the very bottom of the page at jetlasers.org, on the 532nm one. I confess I don't know whether these things automatically turn themselves off/on or if they just overheat and damage themselves. (If the jetlasers.org page tells that also, I apologize.) My suspicion is the...

    Looking for a laser for 600yard application.

    Immo, 600yards, not 600feet. :D But, yes, I have dropped the requirement of the beam being visible from the side. Yep, I am fully aware now that I need the 10x beam-expander.

    Looking for a laser for 600yard application.

    I realize neither of these specifies "DPSS". But which will be 'more easily seen' by a camera at 600yards (The 532nm is about $171 more.) (both have 10x beam expander): 532nm 800mw...

    Looking for a laser for 600yard application.

    I can't give details about the application. I no longer require the beam to be visible from the side. I am working on a different approach now. The 6 inches of beam diameter is very realistic -- take a 1mm beam at the aperture, 2mrad divergence, and a 10x expander and now you have a 4.7inch...

    Looking for cheapest 1watt green laser. Here at $249 -- laserpointerstore.com ?

    Does the laser in post #5 automatically turn off at the end of it's 3minute on-cycle?

    Looking for cheapest 1watt green laser. Here at $249 -- laserpointerstore.com ?

    I will just use an AC/DC converter off my car battery and plug the jetlaser 120AC-to-8VDC adapter into it. done.

    Looking for cheapest 1watt green laser. Here at $249 -- laserpointerstore.com ?

    With Beam expander: MP = magnification factor of beam-expander Di = beam diameter at aperture L = distance to 'target' thi = divergence value Do = beam diameter at L distance Do = MP * Di + L * thi/MP Example: 2mrad divergance 600yard target 1mm beam diameter at aperture 10x beam expander...

    Looking for cheapest 1watt green laser. Here at $249 -- laserpointerstore.com ?

    I am 80yo. What is the correct formula for estimating beam size at large distances, using the specified 2mrad-divergence listed at jetlasers.org? Is it as follows? 2mrad (milliradians) at 600yards: 2e-3 * 600 * 3 * 12 = 43.2inches = 3.6feet??? Is this the correct eqn? And, can I trust the mrad...

    Do they make/sell filter-material that will make a laser-beam more visible to a camera? I have in mind green and blue lasers. For example, for red l

    Fog isn't really an option for me at 600yds...some sort of smoke-trail might be conceivable but seems questionable.

    Looking for cheapest 1watt green laser. Here at $249 -- laserpointerstore.com ?

    What will be the beam size/shape of this beam at 600yards -- 1watt green laser with 10x beam-expander? says $389.99. https://www.jetlasers.org/index.php?id_product=13&controller=product#/1-finish-black/34-power_levels-1w/51-10x_beam_expander-1pc/53-...

    If you buy a laser via paypal from a private-party in China or Japan or Russia, will paypal refund you if you never get the item?

    Do they make/sell filter-material that will make a laser-beam more visible to a camera? I have in mind green and blue lasers. For example, for red lasers they make plastic glasses that filter out all the other wavelengths so that the red is much more visible to the camera:
