Where can you buy green lasers?
You can get them cheapest from Ebay (but u need paypal to buy it).
What was the element neon used for in the past?
they use it neon lights, vacuum tubes, television tubes, lasers, and as a refrigerant
What are negative effects of modern laser technology?
A few disadvantages in lasers are that they can easily blind you, are readily avaliable(anyone can buy them), and also come in very high powers, which can even burn skin! Another disadvantage is for laser hobbyists, lasers can cost ALOT of money! Even a 5mw blue laser can cost well over $500!
What property of the materials used in the computer chips makes them useful as switches that turn electricity on and off?
Computer chips, lasers and many other modern electronic devices are made by etching circuits into microscopically etc
During which stage of the laser printing process is the laser used?
Writing. The laser in the laser printing process is used during the writing stage.
Does semiconductor lasers and laser diodes are similar?
Semiconductor lasers are made with laser diodes, with added circuitry to measure and regulate the diode current/output.
Do optical mice have lasers in them?
No optical mice do not have lasers in them, they use LED's (light emmiting diodes).
What makes lasers laze?
the lasers are pumped or energized by rays of laser diodes. then the laser diodes emit laser light into the semi conductor rod to cause it to laze. the semiconductor rod is stimulated to emit a high coherent light impulse
What are the different kinds of lasers?
gas lasers: helium-neon, argon, carbon dioxide, nitrogen, etc.liquid lasers: dye, chemical reaction lasers, etc.solid lasers: ruby, semiconductor laser diodes, etc.Lasers can be made many ways. Too many for me to list here.

What are Advantages and disadvantages of laser diode?
Laser diodes are numerically the most common type of laser, with 2004 sales of approximately 733 million diode lasers,[6] as compared to 131,000 of other types of lasers.[7] Laser diodes find wide use in telecommunication as easily modulated and easily coupled light sources for fiber optics communication. They are used in various measuring instruments, such as rangefinders. Another common use is in barcode readers. Visible lasers, typically red but later also green, are common as laser pointers. Both low and high-power diodes are used extensively in the printing industry both as light sources for scanning (input) of images and for very high-speed and high-resolution printing plate (output) manufacturing. Infrared and red laser diodes are common in CD players, CD-ROMs and DVD technology. Violet lasers are used in HD DVD and Blu-ray technology. Diode lasers have also found many applications in laser absorption spectrometry (LAS) for high-speed, low-cost assessment or monitoring of the concentration of various species in gas phase. High-power laser diodes are used in industrial applications such as heat treating, cladding, seam welding and for pumping other lasers, such as diode pumped solid state lasers.

What are the advantages of tunable laser diodes?
UV lasers are good for analyizing top surface layers. It has a penetration depth of only a few nanometers, making it incredibly sensitive, even to very thin layers.
How does a laser cutter work?
Lasers used for cutting are rarely found outside of industrial use, as they are extremely dangerous and very large. Laser cutting is done by CO2 lasers or neodymium lasers. CO2 lasers function by energizing a gas mixture of carbon, nitrogen, hydrogen and helium. Neodymium lasers function in the same way as CO2 lasers, except instead of using gas as the medium, they use a crystal with small amounts of neodymium in it.
