High Power Diode Lasers Building a high power laser device?
I'm working on a project that is supposed to use a laser beam to engrave symbols on such surfaces as wood. There're tutorials on the Internet about converting a regular laser pointer into a burning device (uses DVD diode) but its power is not sufficient for my purpose.
Is there any way I could build this myself without having to buy one from the market? e.g using a stronger/weaker diode? If not then is there anything in the market?
Thanks in advance.
I don;t think you are going to be able to engrave with a diode laser, CO2 is by far the most common for engraving.
Amateurs have built CO2 lasers, but it is not a trivial project, doing a search for {CO2 laser homebuilt} will find a number of pages with more information.
You can buy a ready made laser engraver for under $10,000 (maybe well under, if you find a used one or are willing to take a chance with a cheap import) that will not only have the laser, but also the lenses and beam steering mirrors and servos and other stuff you need.
This book summarizes a five year research project, as well as subsequent results regarding high power diode laser systems and their application in materials processing. The text explores the entire chain of technology, from the semiconductor technology, through cooling mounting and assembly, beam shaping and system technology, to applications in the processing of such materials as metals and polymers. Includes theoretical models, a range of important parameters and practical tips.

In the thirty years since the invention of the CO2 gas laser, the major design issue has shifted from how to obtain the desired power level to how to achieve reliable operation. At the same time, the opening of many laser development facilities in the Former Soviet Union has allowed their achievements and design approaches to be understood and appreciated for the first time. Further, the industrial laser user community has identified a number of emerging applications at higher power levels (1520 kW) than are attainable by most commercial devices. In High Power Lasers Science and Engineering, the designers, developers and users of highpower gas laser systems discuss design approaches, methods of enhancing performance, new applications, and user requirements.

This book covers the device physics of semiconductor lasers in five chapters written by recognized experts in this field. The volume begins by introducing the basic mechanisms of optical gain in semiconductors and the role of quantum confinement in modern quantum well diode lasers. Subsequent chapters treat the effects of built-in strain, one of the important recent advances in the technology of these lasers, and the physical mechanisms underlying the dynamics and high speed modulation of these devices. The book concludes with chapters addressing the control of photon states in squeezed-light and microcavity structures, and electron states in low dimensional quantum wire and quantum dot lasers. The book offers useful information for both readers unfamiliar with semiconductor lasers, through the introductory parts of each chapter, as well as a state-of-the-art discussion of some of the most advanced semiconductor laser structures, intended for readers engaged in research in this field. This book may also serve as an introduction for the companion volume, Semiconductor Lasers II: Materials and Structures, which presents further details on the different material systems and laser structures used for achieving specific diode laser performance features.* Introduces the reader to the basics of semiconductor lasers* Covers the fundamentals of lasing in semiconductors, including quantum confined and microcavity structures* Beneficial to readers interested in the more general aspects of semiconductor physics and optoelectronic devices, such as quantum confined heterostructures and integrated optics* Each chapter contains a thorough introduction to the topic geared toward the non-expert, followed by an in-depth discussion of current technology and future trends* Useful for professionals engaged in research and development* Contains numerous schematic and data-containing illustrations

Enhance your Presentation Effects With Laser Presenter
It's downright incredible how cheap laser pointers are these days. Lit up 30 years ago the laser diode is the basis of all of the world's cheap lasers, you can get a decent one on EBay less than 10$. Laser pointer is very useful, and one of its most popular usages nowadays is wireless laser presenter.
At some point or another in everybody's working life, a presentation in front of one's peers, colleagues, or customers is inevitable. Laser presenter offers a very nice alternative to remaining tethered to a PC while cranking through the PowerPoints. In fact, as the product name so ably illustrates, the wireless laser Presenter not only gives presenters the ability to walk away from the PC showing their slides, it lets them highlight key information items on their foils with an intense spot of bright light.
Most wireless laser presenter combines office help functions to simplify the process. Functions like advance or reverse the slide deck, scroll page up and down and more. There are two kinds of technology - FR and Bluetooth wireless technology both enables 10 meters effective range. To handle it, simply plug in the USB dongle to the PC, then pairing the laser presenter with dongle, ok well done. Due to high efficiency, though powered by two or more battery cells, it can last for days to use.
Green laser pointers are nothing special these days, either. People think green laser is more visible because human’s eyes are somehow 10 times more sensitive to green light than red light. Even the green beam can be seen at some high power green lasers, and the dot is clearly visible on bright surface even sunlit surface. Choose a green laser will helps your audience easily catching the dot and thereby your points in presentation.
