In summary, the person is looking for websites and information on how lasers work and what they are used for. They are looking for websites that have information on theoretical aspects of lasers and not just simple information on what a laser is.

Hi!

I just wanted to know if you guys can help me with a project I have. The project is on the "Engineering Uses of Lasers." All I'm asking for is some decent, usable websites and information. Most of the sites & journals I've looked through either have purely theoretical work or simple information on what a laser is doing rather than why and what makes it do these things. I really hope you guys can help me here.

Thanx... :smile:

If you want to know why and how it works that is different than what use it is in Engineering. Lasers are generally used for precision work where you need to be very precise. Lasers are precise because the light is all synchronized and focused in a small point. They are also used for measuring because they are precise.

Ok, I understand what u say but the project is not a mickey mouse school projecty - we kinda need to know what the use is, how it works, the maths behind it and why is it used. It's easy to find each point individually - puttin them together logically is a slight problem here! that's why I was hoping some of you guys can help! :smile:

You seem to have divide everything into "theoretical work" or "simple information on what a laser is" and say you want "why and what makes it do these things". That IS "theoretical"! What you really want is "elementary" theoretical information.

I "googled" on "elementary laser" and got a number of sights that might help you: in particular

(I remember when lasers took up whole rooms with rigid safety rules- now you can buy them at a hardware store. Of course, I took freshman physics from Charles Townes- My God,I'm old!)

FAQ: Exploring the Basics of Lasers: A Resource Guide for Beginners

What types of lasers are commonly used for scientific research?

There are several types of lasers that are commonly used in scientific research, including gas lasers, solid-state lasers, and semiconductor lasers. Gas lasers, such as helium-neon and carbon dioxide lasers, are often used for their high power and precision. Solid-state lasers, such as ruby and neodymium-doped yttrium aluminum garnet (Nd:YAG) lasers, are known for their stability and efficiency. Semiconductor lasers, such as diode lasers, are compact and cost-effective options for specific research applications.

How can lasers be used in medical treatments?

Lasers have a wide range of medical applications, such as in surgical procedures, cosmetic treatments, and therapeutic procedures. They can be used to precisely cut or remove tissue, seal blood vessels, and treat skin conditions. Lasers can also be used to stimulate tissue repair and promote healing.

What are some safety considerations when working with lasers?

When working with lasers, it is important to follow proper safety protocols to avoid potential hazards. This includes wearing appropriate protective gear, such as laser safety glasses and lab coats, and ensuring that the laser is properly calibrated and maintained. It is also important to follow proper procedures for laser operation and to be aware of potential hazards, such as accidental exposure to laser beams or electrical hazards.

How can lasers be used in materials processing?

Lasers are commonly used in materials processing for cutting, welding, and surface treatments. They can provide precise and fast cutting of various materials, including metals, plastics, and ceramics. Lasers can also be used for surface treatments, such as laser marking and engraving, to create permanent and high-quality markings on materials for identification or decorative purposes.

What advancements have been made in laser technology in recent years?

In recent years, there have been significant advancements in laser technology, particularly in the fields of materials processing, medical treatments, and scientific research. These advancements include the development of more powerful and efficient lasers, the use of new laser materials, and the integration of lasers with other technologies, such as robotics and artificial intelligence. There has also been a focus on developing more compact and cost-effective laser systems for wider accessibility and applications.
