Will it lead to new technologies for surface modification? Challenge to Black Marking

At a bar in Sanjo City….
Niigata is a great place to drink, and I go out to drink quite a bit! That’s where we often discuss things.
I am quite obsessed with inexpensive nano-periodic structure creation.
No matter how many lasers can do black marking with pico-second and femto-second lasers in the market, the prices are not as high as those of laser markers.
The price of laser marking is too high to use, right?
That’s why it has been a challenge for me, known as a genius in laser processes, for a long time.
This time, I tested an inexpensive laser of about 20 picometers.
So, please take a look at the results. I achieved the results as shown here!
Finally, the black marking is done. And it was only one drawing.

Boss is here.
Is it true?
Yes, please take a look at this! (Where were you?)

And, LIPSS is ready!
Ooh!
Hmm?
That looks grayish, not a periodic structure. First of all, the actual laser-processed photo is smaller than SEM photo.
At this busy time of year for laser technology development, we’re not going to do anything unnecessary! Why don’t you just use a femto-second laser?
Check. It’s on you!
