Great video - the one suggestion I would make (I'm quite shocked there does exist something to suggest), is that you surely to run the cooling fans (at lest those for electronics), at significantly lower - read barely audible - speeds
You need a CCD camera instead of CMOS to see the laser. That will eliminate rolling shutter. I had the same problem while filming a Wimshurst machine. Additionally you need to slow down the shutter speed as much as possible and then balance exposure by putting a ND filter in front of the camera.
Yes that is fascinating keep up the good work.
Excellent video, as always! I greatly look forward to the next in the series. Fascinating effect with the hollow beam cross section at low powers. Will you be looking for a lower inductance pulse ignition transformer for stage 3, or are you going to try parallel injection, or perhaps even RF ignition? I shared this video on LPF for all to enjoy! -Sig
Very interesting video as well!.. Thanks for taking time to share. I like your work. I would wish to have you as my neiborhood !
ahh once again really awsome. Too bad we couldn't see the lase but aside from that really interesting. Isn't rhodamine used as fabric dye?
Fascinating - thank you for sharing your expertise
the reason your camera isn't picking it up is because the camera is set to a very fast "shutter" time, so most of the time between frames is not captured
You can still have emission from the triplet state... that is phosphorescence
what is the inductance of that series high voltage trigger transformer? if you want shorter pulse, maybe its good to consider using other methods of igniting arc in a tube rather than a transformer that would introduce inductance to the circuit and prolong a pulse?
Watch the later pulsed dye laser videos where I address just that.
How do you split the cap into three ???
That capacitor is actually an assembly of three individual capacitors with a common ground within a single metal case.
@@TechIngredients so I imagine cutting it open around the top edge would do it .
You could, but why? It's nice to have a single unit with three different energy capacities.
@@TechIngredients I wanted to put them in series. Quick list of questions,
1. What is the voltage and capacitance for your big flash lamp capacitor for the big dye laser?
2. Where are you getting your annealed quartz tube for your flash lamps?
3.would you like to hear about an idea I had that is for detonating avalanches using solar panels and HHO gas. It’s basically a remote controller system that would melt snow and use the water in a hho cell to create gas pockets underneath snow and electronically detonate creating a chain reaction causing controlled avalanches. Just an idea,,
20 kV, 100uF. A local glass shop did this for us.
Probably not going to work due to engineering issues. HHO has an extremely low energy density, so a large volume is needed. Storing up that gas while it is made can obviously be dangerous and it has to be retained in a bag or balloon that is protected from the wind. Without that containment it can flow anywhere and placing it under the snow requires a significant excavation in a hazardous location.

Woah, MEGA laser geek! Subbed! I was given a SpectraPhysics pipe-lining laser when I was about 16-17 (1990s - I am 40 now) and was also given a lot of HeNe lasers. I took all of these apart, amazing memories - lasers are SO much fun! :D
God bless you, thank you, Matt, England. :)
