So, I have been away making a new fully homebuilt laser. It is a manganese metal vapour laser. The laser tube is fully homebuilt. It is a self-heated tube. The main part of it is a ceramic bore tube with 14mm inner diameter and 60cm long. This tube is sorrounded with a layer of ceramic wool...

The pumping chamber is still on sale on e-bay. https://www.ebay.com/itm/K301V-YAG-Cavity-Pumping-chamber-130W-1064-nm/112982983816?hash=item1a4e4f8488:g:MBcAAOSwmcBa8v43:rk:3:pf:0 Also I want to add for sale some custom made low pressure mercury lamps, that had been made by my fellow...

I tried looking for it through "565 nm laser" search query. but didn't find it. I'd like to buy a couple of them to have a volatile exchange fund, for converting them into gas lasers then:yh::yh:

Is there a chance that these lasers will appear on e-bay soon?

I think that cooling it with a fan will not harm.

Bump!

This is normal for the MOT. All of them become very hot because the iron core works very near to the state of magnetic saturation. To reduce the heating it would be good to add a couple of tens of turns in the primary.

I think I will return to this project soon, as I've made the GOS1001 laser working. I've drawn a rough optical layout of the green laser. It will utilise 2 130W pumping chambers an a big lithium niobate crystal. Will this layout work? And where can I get a curved HR mirror for 45deg reflection?

Yes, it generates quite a lot of heat. Normal rate of fire is one shot in two to five minutes, depending on the pumping energy. So I adjusted the time of the caps to recharge to match this value. And 30 liters of water become warm after ten shots at 24 kJ. At this point output energy starts to...

Some more holes in steel plates

Yesterday I managed to push 24 kJ of pumping energy. Estimated output is about 250-300J. Anyway, it cannot penetrate 3mm of steel from a single shot. The lens is with bigger focal lens and is not damaged now.

Bump! this pumping chamber is still on sale...

Thanks!

Here I'm starting a thread about the most high-energy laser that had ever been manufactured commercially for general lab use. The GOS-1001 Nd:Glass laser, that is rated for 1000 J of output energy! And it is the true peak of my collection. A few days ago I managed to get first coherent photons...

Very cool!

It looks like that a HR from a pulsed laser should be fine for this. I've got a couple of them.

AFAIK, I've got several mirrors for 1064nm, HRs and OCs. Do you know what reflectivity do you need for an OC? I have some with t=16%, 20% and probably 25%. Also I've got OCs with t=50% and 70%, but these are for pulsed lasers. PS: the flow rate in the first loop is 25 liters per minute or...

Hello Here I'll show a typical russian chiller for a lamp-pumped 250W YAG laser. The tank is filled with distilled water that is pumped into the water jacket of the YAG rod with the pump on top of the tank, and through the coils of tubes cold water from the tap flows to take away heat from the...

27) The laser tube that I've been hunting on for several years -- really big CVL tube! It is also sealed-off self-heating tube with the output of up to 30W on both lines, it is called GL-201. It needs at least 4 kW of input power, so it will be quite tricky to run it. The tube is 1.3 meter long...
