This is a re-posted video showing the operation of a KTP pumped dye laser. An explanation is given for the physics underlining this type of laser. The performance, including power output and beam parameters, is demonstrated. Future incorporation of this laser into a multicolor laser projector is outlined.
Excellent Work sir! Yellow color is already close to the peak sensivity of the eyes but showing a 10 watts yellow beam is simply amazing! I will definitively follow that great project !
Thanks for the great explanations too.. look like if you and Rocketman340 would live next door it would result in an intense Laser diy Party!!
Another great build and video. Thanks for sharing... And if that ends up taking up too much room in your shop, just let me know and I'll help take it off your hands... ;)
Cool laser. You seem to be concerned about dye flow. You could go to the next size lines and fittings, and perhaps redesign your dye cell so it doesn't have 90-degree bends. You could user lower pressure to do the same thing, and the dye would stay cooler. Computer water cooling hardware common is cheap now.
Also, as the water-coolers have learned, certain types of tubing--I think even certain types of tygon leach plasticizes.
if the goal of pumping the dye solution is just to move new dye into the focus quickly
then how about just using a fine jet? maybe using a rather large dye cell is
to reduce turbulence?
There are free jet flow dye lasers. The lack of windows makes it possible to achieve very high energies, but they can be very messy.😕
The age for a portable version isn't there yet
Very interesting. I have always assumed high divergence characteristics were mainly due to the lasing medium length. For instance, a gas laser with a long lasing medium having low divergence and a short lasing medium, such as a laser diode having wide divergence. Why does a dye laser have such a narrow divergence in comparison to pumping an SHG crystal? I would assume that since they are both being pumped with a coherent source and both similar in size mediums that they'd have similar beam characteristics. This is obviously not the case.
Also, very interesting info on stacking the beams on their fast axis. I've never heard of that but It makes perfect sense. I'll have to experiment with that sometime.
NO GOGGLES ??? THIS GUY KNOWS WHAT HE IS DOING SO IM TALKING TO EVERYBODY ELSE
THATLL TEACH ME TO COMMENT BEFORE THE END BUT ITS STILL GOOD FOR EVERYBODY
I LIKE THE QUOTE "DONT LOOK INTO THE BEAM WITH YOUR GOOD EYE"
Ok but why the caps?
570nm and it would be true yellow :)
That's correct

After watching this, i thought to myself if i ever win the lottery, this is what i would like to as a hobby at home. Unfortunately money cannot buy this mans experience and knowledge which i envy, i will just keep watching in absolute amazement, thankyou.
