Sorry I seem to have missed most of these comments as e-mails were going to an inactive address. I fixed that. This is a 5000 watt laser. We can also cut good 1" steel with a 4000 watt laser.

This resonator is 5000 watts. The beam is a heat ray in the infrared range so you cannot see it with your eye. The unfocused beam can travel pretty far and still deliver a significant amount of power that could heat up or burn things but probably not cut them. The military has a number of laser weapons developed in recent years using different types of lasers.

The beam that comes from the resonator on this laser is about an inch in diameter. When it comes into the cutting head it is focused on a small spot on top of the material in order to get the power density that will cut steel. There are a significant number of safety devices built into the machine to make it difficult to cut your hand. Indeed you could sever a finger if you could get it under the head.

Imagine that on your skin!

Low powered lasers are used for surgery because they easily cut flesh and also cauterize the cut greatly reducing bleeding. This high powered laser has numerous safety features to make sure that you are not exposed to the beam. It is surrounded by a safety enclosure. The beam only comes on when the head is in close proximity to conductive material like steel. During maintenance it takes two hands to turn on or flash the beam.

Shouldnt they drop out?

[rickneff58]

@sk8wnec The CL-850 has a pretty dense cutting grid that keeps many parts from dropping. Once the part has been removed you can see a grit tip under the area where the slug would have been able to drop. Small slugs will usually drop through especially in thin material. In 1" thick plate most slugs get hot and with a small kerf do not drop readily. Only a little persuasion will get the parts out of the sheet.

Insane power, i mean 1 inch gees..

The future cam so gradually I didn't even relies when it was here.

Its light cutting through 1 inch of steel...

Placed on the eye

@rickneff58 Rick, can you tell me what type of steel you are cutting in this video? we are trying to cut 1" A572 and we are having trouble with teh edge quality. thanks Shawn

Wow..makes a plasma cutter look like a Bic lighter: awesome!

[kalinte007]

lokking at the finished product makes you wonder how did they manage to make such items 10 years ago? forged steel perhaps

@fizzy1972 Rofin DC030 & DC035 have a slightly larger beam and cut thicker materials much better (Stainless 15mm on a Prima Platino). The DC040 is just a monster, have cut Al 4mm at 4000mm/min with N2, MS 30mm and still very good at thin sheet.

Nice cut, i've seen most lasers struggle with 20mm mild steel. I've haven't heard of the Cincinnati CL-850, what is its maximum power and does it use gas?
