Laser Cutting for Dense Materials: Q&A

In summary, the conversation discusses the possibility of using lasers to cut up to ten feet depth into dense materials such as rock and steel. The person asking the question is aware of research being done on using lasers for oil and gas drilling, but is looking for more information on the capabilities and availability of such lasers. The responders mention technical challenges such as the Rayleigh length and the need for high laser power, and also make a joke about the late Edward Teller's expertise in this area.

Hi,

Not sure if this is the correct section to post my question, so if not apologies in advance. I'm wondering if there are lasers (need not be for consumer or general manufacturing purposes) that have the capacity to cut up to ten feet depth into dense materials like rock and perhaps some steels? All I have been able to find are engraving level lasers. I do know there is currently a research program studying the potential for using lasers for oil and gas drilling, but I have not been able to find any information on the lasers or where they are in terms of their research.

Any help is appreciated,
Boogleboog

Too bad Edward Teller died some years ago.
His answer would've certainly been:" Yes! Give me 100 billion dollars and I´ll make it!
Jokes aside, cutting ten feet posses many technical problems. The Rayleigh length is the zone where the laser beam has the highest intensity. Unfortunately, a Rayleigh length ten feet long demands a large beam diameter unless you have an X-ray laser (bring Teller back!). In order to achieve high intensity, this large beam diameter calls for a very large laser power.
Some chemical lasers, designed to destroy missiles, had output power in the mega watt range. I wonder whether this is high enough to cut through ten feet of steel.

Thanks Gordianus,

Unfortunately, for what I have in mind a large diameter would not work. Also, relative to what you mean by 'large' power, that would potentially from a pragmatic standpoint undermine my fantasy tool. Thanks for your reply and the bit of info regarding the Rayleigh length.
 

FAQ: Laser Cutting for Dense Materials: Q&A

What is laser cutting?

Laser cutting is a manufacturing process that uses a high-powered laser beam to cut through dense materials such as metal, wood, or plastic. The laser beam is controlled by a computer and can make precise cuts in various shapes and sizes.

What are the benefits of laser cutting for dense materials?

Laser cutting offers several benefits, including high precision and accuracy, smooth and clean cuts, and the ability to cut through thick materials. It also allows for complex designs and reduces the need for post-processing.

What types of materials can be cut using laser cutting?

Laser cutting can be used on a wide range of materials, including metals, wood, acrylic, glass, and more. However, the type and thickness of the material will determine the power and settings needed for the laser cutting process.

Is laser cutting safe?

As with any manufacturing process, safety measures should be taken when using laser cutting. However, laser cutting is generally considered safe as long as proper precautions are taken, such as using protective eyewear and following recommended protocols.

How does laser cutting differ from other cutting methods?

Laser cutting offers several advantages over traditional cutting methods, such as increased precision, speed, and flexibility. It also does not require physical contact with the material, reducing the risk of damage or contamination. Additionally, laser cutting can be automated, making it a more efficient and cost-effective option for cutting dense materials.
