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

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

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?

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?

Great explanation on aligning. What kind of source excitation you're using for the YAG crystal, xenon light?

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?
