520 nm vs 532 nm laser who is better ?






And I will shine this laser in realy long distances like 15-30 km and its suitable for 10x beam expander maybe sometimes I will use this laser for burning
 
They won't keep full power output for very long, when they warm up from running them a minute or two, the power begins to drop, if too cold, the power drops, maybe half of the rated output or less whether too cold or too warm. If far too cold, hardly any output at all, same if far too warm. Optotronics makes one which is more stable, but also more $. The only fully stable DPSS laser pointer I am aware of was made by Laserglow, the Hercules has a TEC built in to keep the crystal at a stable temperature, but again, even more $ if you can even get your hands on one due to import restrictions in some countries.

I will get the 520 nm not dpss 532nm
 
I think you should get both, and see for yourself. Which one first? The 520 nm is good, but a beam expander is a must if you want the beam to stay fairly tight for a long distance, otherwise without at least 3 X expansion, it won't hold very tight, is actually awful in that regard without a beam expander. The only thing is some people don't like a fat beam, with the beam expander the beam will be thicker than a DPSS laser, so it won't appear as brilliant coming out of the pointer, but in the far distance, will remain bright in the night sky, if you were to use it outside.

Some members refuse to use a laser outside, or point into the sky, that has it's own problems, if you accidentally flashed am aircraft and were caught, terrible fines and jail time. Others just don't want neighbors getting upset. I've been yelled at once by a neighbor who was annoyed to see the beam, even though it was not going in their direction.
 
Huh. My neighbors have always been very supportive of my nighttime beam shots outside. I am fully aware of the flight paths aircraft take here. Besides, I have many tall trees that act as a beam stop too.

I have a dpss laser now but its 3 years old and the lens is scrached alot its using arcrilic lens.
And Im planning to buy a sanwu striker 3w and weak green laser in september but sanwu out of stock and now Im planning to get a jet lasers Pl-e mini 1w 520 nm laser
 
And in turkey there is no law for shining your lasers to your neigthbors yard
 
Homebrew hijack hack alert: I'm going to try to make a DPSS monster here soon, I have a nice NOS 806.5 nm 50 W FAP with a very large 4x4x5 mm YVO4 crystal as well as SMA coupled 808 nm focusing lens designed for that crystal and now this week, a 8x8x15 mm KTP crystal in a Coherent oven. Going directly into YVO4/Vanadate should be efficient enough, if it isn’t I have plenty of pump power.

I don’t expect great things first try, but will be testing and seeing what can be produced, will likely have optic issues to work out before much power output using these somewhat random parts (what I could find surplus at a reasonable price), but I have a lot of different crystal lengths and sizes to try for both KTP and YVO4 from collecting them over the last few years.

Even if I cannot produce much green with these parts, if I can get a good amount of 1064 nm out of the YVO4, I will be happy with that and just build a DPSS for 1064, it would be handy to have a 1064 nm source with a few watts of power which I can focus into crystals to see what they do. I probably will only run the 50 watt FAP at half power to reduce the size of the needed heat sink. The YVO4 crystal came out of a HIPPO 1064 nm diode pumped laser producing up to ten watts output, that amount of drive ought be be about max for it.

When I start on this and have some results, I will make a new thread, I won't be high jacking this thread more :)

Why aren't asking JetLasers themselves? Have you tried messaging them and having issues?
Since your in Turkey I can't answer as i'm in the US..

Exactly.

And What is the shipping price on jetlasers

Why do you keep asking this question ?
Use common sense and ask JetLasers. Nobody on LPF can answer for JetLasers.
Stop asking on LPF. LPF is not JetLasers shipping department or shipping agent or a shipping company of any kind for anyone.
 
Because I dont see any contact us button on their vebsite
