Powerful homemade diode pumped Pr:Ylf laser!
In this video, I show you a laser setup using a Pr:Ylf crystal. This crystal can emit at multiple visible wavelengths (green, orange, red and more) which is quite rare for laser gain media.
► This setup also reaches quite high output powers (above 300mW) and shows some beautiful TEM modes!
► If you want to know more about this laser, I've written an article on my website about it: www.sci-projects.org/blog/diode-pumped-prylf-laser-emitting-at-640-604-and-523nm
► This project also has a GitHub-Page for more details: github.com/NiklasHammerstone/PrYlf-Laser
►If you liked this video please give it a thumbs up :) If not, give it a thumbs down and/or write in the comments why so.

How to align pulsed lasers with plane mirrors
Просмотров 1,3 тыс.2 года назад
Laser resonators with plane mirrors (typical for Nd:Yag or ruby lasers) are notoriously hard to align without special equipment. In this video, I show how it can be done quite precisely in a home workshop like mine. All you need is a second collimated laser (like a HeNe) and an adjustable mirror. This method works quite reliably and without much prior experience in this field. Great videos abou...

HOW to make a ring using ONLY HANDTOOLS!!
With some strategic painting, and a different template tsuba, you could make a repilca of Tanjirou's sword quite easily
I need this wooden sword
It's would be great to see diy DPSS or fiber laser which could engrave metal!
Amazing work, I cant wait to make mine now
Learning this for zombie apocalypse
please without powertools PLEASE!
also how to make the cover of the katana
don't have the tools😔... how do i make it?
very creative!! Been wondering how this could be done without a band saw
The pdf
WHERE DID YOU ACQUIRE THE ANAMORPHIC PRISMS.
make a real steel katana
Now how do i drill straight into that center😂
The problem with the gluing stones, especially clear ones like that the vapors from the superglue make the stone look cloudy
That can be true if you are unlucky. One could try UV-curing glue. We use it in for glueing laser crystals, so no outgassing :)
How to make a wooden sword with no power tools proceeds to show the most diabolical weapon and tools
i love it
I burned two laser pointer too over current
I tried this with red laser...the sine wave stay is my eyes to five week... i use speaker to move mirror Y and laser rotation motor X of left right (wire less power inductive coil). Like much your gcode ideia. Tanks for share!
Its a cool way to make a sheath I made mine with popsicle sticks and glue(gun)
would be cool if you done this in the dark and used fog machine so we can see what the beam truly looks like
if the mode volume is not coinciding with the pump volume then is there still emission happening? i thought there would not be any
If the pumped volume is not coinciding with the mode volume, there will still be fluorescence, but no laser action.
@@WoodenWeaponry ty but it is funny how we are still seeing the intense lines of both volumes as if there is lasing and stimulated emission still happening although no output , there really should not be such sharp line if the resonator is not aligned and should only appear once mirrors align
Ah, I see what you mean. The fluorescence comes from the pumplight entering the crystal (first stripe) and being reflected and focussed back into the crystal by the curved OC mirror (second stripe).
@@WoodenWeaponry ahh ok
in your diagram it shows the laser output being divergent, so do you need a collimating lens after the oc or is this only exaggerated?
is it possible to either tune it or use another diode in order to get the green emission instead?
they said a ruby can not operate in cw mode as it has something to do with the energy level of the chromium atoms and their short excited state time etc ,,i need to stop listening to ppl and understand these things myself to know if it is possible or not because i too ever since i been fascinated with lasers always wondered if it's possible to run a ruby cw
Question: how long in Inches did you need for the Tsuka-Ito?? (handle wrap)
I can't believe it😱😱😱
what a katana
Hi, very good the home project. Would you please tell me the distance of the back mirror and the front mirror with the laser rod, or how to calculate the distance. Thanks. William.
Bang tolong buat tin dong bang plis daera ku di bumiarjo bang nama ku dewa❤❤😂😢 su pakek leng kab
hmm is the wavelength different than the typical 694nm you get using a flash lamp because you are using another pump source and its absorbing and emitting something different frequency?
No, the excitation source has, in this case, no influence on the emission properties.
@@WoodenWeaponry well you said the emission is 700nm not 694
Ah then that was an approximation/rounding on my side, sorry. No, it is still 694.
@@WoodenWeaponry ok i should have remembered that each lasing medium requires the same unique energy no matter the source
in your schematic at 9:50 why does it show the output beam diverging after the oc? is this what actually happens if so do you not need a lens to collimate it?
nice but would have been nicer if you had it running through smoke in the dark with the cam facing the output side to really see what the beam looks like
huh so why have i always heard and read that ruby cannot be cw with an arc lamp or cw lamps?
Wowwowowowoowwowo❤❤❤
Bro I don't have this instruments so I managed with small handsaw blade which took many days to prepare 😅😅😅😅
one reason why the retail blue diode engraving laser systems have retangular spot shapes is that they are not truly "beam combined". in these systems, the term used is "Knife edging" and its *not* the same approach as the coherent or spectral beam combination that is used in the "serious" technial laser designs in commecrial systems (commonly used in Fiber-Pump modules, eg see the IPG photonics website, where they have images of de lidded modules showing their internal optical setups) essentially the rectangular beam is created when multiple beams *DO NOT* follow the same perfectly co-axial path/alignment, and actually allign *slightly* off-center, spaced laterally relative to each other (in addition to a "dumb" aperture that may be filtering as well) to the naked eye, these arrangements can appear to be similar or identical. a few of the stage laser ompanies have diagrams explaining the whole "smeared out" imperfect overlap "Knife edging" approach
Danke!!!! Just the tip I was looking for.
great explanation and demo of the DPSS. Can you explain more how you made the optics and would it be possible to simply get a ruby rod and cut it to size then surface grind the edges flat?
use high voltage stepper driver, higher voltage make motor more stable in high speed movement... like 48v supply driver
6:40 - Wow, that makes sense. Thanks for this great explanation. What type of focusing lens did you get? Do you need to calculate which anamorphic prisms and focusing lens needed before buying? If so what are the calculations?
DIY Simple Looser Scanner with step by step
Great explanation on aligning. What kind of source excitation you're using for the YAG crystal, xenon light?
Thank you! Yes, I used Xenon Flashlamps. Krypton is better as I hear, but Xenon worked well also.
Mas caraperdanng
Bro where do you download the template
Thank you. Such an awesome miniature prototype.
Thanks Nik. This is a really great way to easily make a sheath!
perfect done!
What steel did you use?
Is it sharp?
