The other main difference between red and green lasers is the complexity of their construction. In simple terms a red laser consists of a circuit board, red laser diode and a focusing lens. Green lasers on the other hand are much more complex because there are no green laser diodes that can be used. Instead an infrared (808nm) diode is used with a combination of special crystals and a filter to produce green laser light.

Examples of other types of Green and Red lasers

Red lasers

-red gas lasers – for example Helium-neon (HeNe) and krypton lasers

-Titanium-sapphire lasers – these lasers mostly emit in the infrared spectrum but can be tuned down to 650nm.

-Praseodynium doped unconversion lasers – emit light with a wavelength of around 635nm

-frequency doubled lasers – apply the phenomenon of using an input wave to generate a wave with twice the optical frequency. Also called second harmonic generation lasers

Green lasers

- Argon lasers – the highest power for an argon laser can be obtained at 514.5nm. Can acheive over 20 W but energy efficiency is very poor.

-Helium neon lasers – several milliwats at 543.5nm

-Copper vapor lasers – comparatively higher powers at 510.6nm

-Erbium doped upconversion lasers- are around 550nm and normally have an output of tens of milliwatts

-Dye lasers – can be tuned to operate in the green spectral region.

Red Laser Trivia : Red lasers and Blue lasers in Dvd’s

Even though blue lasers have taken the DVD world by storm with vastly superior memory storage etc, red lasers will not be completely phased out. Research on carried out at the end of 2005 on the comparison of blue and red lasers in DVD’s had the following interesting results

-blue lasers were shown to have no significant gain in accuracy over red lasers

-blue lasers are approximately 10 times more expensive than red lasers

-red lasers are longer lasting and more durable than blue lasers
ansistor elements permit the extension of Moore's law to technology nodes beyond what might be allowed in silicon. Long before the time when this might be achieved, nanotubes in the form of films and networks should supplant silicon in a broad array of (hopefully) revenue-generating applications. The work by the Northwestern group should also greatly help those efforts.
Scientists from Tokyo University have just revealed a reliable method to inkjet print dots of one micron on to flexible film. It is described in Proceedings of the National Academy of Sciences. This is needed to conserve the very expensive inks used in printed electronics and to improve the electronic properties of printed electronic devices by reducing key dimensions such as the channel length of transistors. These are being developed by 360 organisations, half of them academic, and they are likely to be the biggest printed electronics market, just as silicon chip logic dominates conventional electronics expenditure. Indeed, in conventional flat screen displays, higher processing temperatures, increased manufacturing costs, and a higher price for the consumer are being incurred in order to improve performance and the new form of inkjet printing is expected to help to reverse this malign trend.

SPEED OF "ELECTRICITY"
1996 Bill Beaty

How fast does electronic cell phone flow? Well, it depends on what you mean by "electricity." The word Electricity has more than one contradictory meaning, so before we can talk about its flow, we have to decide on which of several "electricities" we really mean. For a discussion of electric current, see below. But for articles about fast-flowing electromagnetic energy, see the FAQ, or this email discussion.

OK, then how about this. When we turn electronic cell phone on a flashlight, something called an "electric current" begins to happen. Inside the flashlight bulb, the thin filament-wire gets hot because there is electric current in the metal. This current is a motion of something. How fast does this "something" move? This question can be answered.

The quick answer
Inside the wires, the "something" moves very, very slowly, almost as slowly as the minute hand on a clock. Electric current is like a flow of syrup. Even maple syrup moves too fast, so that's not a good analogy. Electric charges flow as slowly as a river of warm putty. And in AC circuits, it doesn't move forward at all, instead it sits in one place and vibrates. Energy can flow fast in an electric circuit because metals are already filled with this "putty." If you push on one end of a column of putty, the far end moves almost instantly. Energy flows fast, yet an electric current is a very slow flow.

The complicated answer
Within all metals there is a substance which can move. This stuff has several different names: the Sea of Charge, or the Electron Sea, or the Electron Gas, or "charge." We often call it "electricity." Calling it "electricity" can be misleading because charge is not energy, yet many people think that electrical energy is the "electricity." It can be misleading because the Sea of Charge exists within in all metal objects, all the time, even when the metal has not been made into a wire and is not part of an electric device. If the Electron Sea is "electricity," then we must say that all metals are full of electricity. Better to call it by the name "charge-sea," and avoid the misleading word "electricity".

During an electric current, the wire stays still and the sea of charge flows along through it. When the flashlight switch is turned off and the lightbulb goes dark, the charge-sea stops moving forward. Even though it stops electronic cell phone moving, the charge-sea is still inside of that wire. If the flashlight is again turned on and two light bulbs are connected in parallel instead of one, the electric current will have twice as large a value, and twice as much light will be created. And most important, the charge-sea of the electronic cell phone battery's wires will flow twice as fast. In other words, THE SPEED OF THE CHARGES IS PROPORTIONAL TO THE VALUE OF ELECTRIC CURRENT; small current means low-speed charge flow, large current means high speed. Zero current means the charges have stopped. Note however that an electric current does not have just one speed. Charges speed up when they flow into a thinner wire. The high current in the lightbulb of a big flash-lantern will be much faster than the same current in the conductors in the lantern. Even though an electric current is a very slow flow of charges, we can't know the actual speed of flow unless first we know the *value* (the amperes) of the current in the wires.
