Is the beam profile round? Or is the beam truncated by the aperture?

In the official Sanwu thread Podo said they are looking into fast axis correct some time ago.

What does this word "quimical" mean?

As I recall Poco wrote in his thread they are looking into beam correction.

Yes.

I took a look a the site but did not see a pointer available. Where would I find it on their site? Thanks

Researchers have demonstrated a record-high laser pulse intensity of over 1023 W/cm2 using the petawatt laser at the Center for Relativistic Laser Science (CoReLS), Institute for Basic Science in the Republic of Korea. It took more than a decade to reach this laser intensity, which is ten times...

The peak is 555nm.

It comes down to power density. A variable beam expander works because it can focus at a distance. Correcting the beam profile with beam shaping optics also helps beams that are not TEM00. See this 13 year old vid.

A laser bong. Why didn't I think of that? https://mashable.com/review/hitoki-trident-laser-bong-review/

Though burning stuff with a laser is astonishing as watching paint dry, I must say this certainly surpasses paint drying. Also, what really is impressive is the work that went into using a Cassegrain telescope as a beam expander...

I wrote this in 2017. "One thing no company is offering are lasers with beam shaping optics. Personally I quite find lasers that produce a line rectangle and not a round spot or something close to that a very compelling reason not to purchase. I had my eye set on buying a 462-465nm laser until I...

Should you put together a real UV laser a novel way to collimate the beam would be to shine the beam through a flourescing fluid like quinine.

By the way. Do not think of using soft metal on glass lenses too.

That 405 nm laser can fluoresce and phosphoresce many things you would not think could. Keep it to see.

Raising the dead is ok when one adds relevant information. I though you did

I've looked a many pointers and not once have I had any problem. That may be do to the pointers not being turned on at the time I looked at them. As for your paranoia that's not possible. You see, paranoia only occurs when one thinks other people are talking about one's self or plotting against...

Confirm by actually measuring with a tape measure.
