RED lasers have became incredibly cheap and the price drops were driven by production of the lasers for OTHER uses in dvds, cd players etc. This mass market production is the only reason red lasers have become so cheap as the actual market for lasers as presentation tools is tiny compared to the overall market for dvd/cd/barcode scanners etc.
YELLOW lasers offer NO advantage over green for brightness; they have little other uses other than for presentations and the novelty factor of that, and as a result there has not been any need for mass scale production so volumes are VERY small. I believe there have been less than 500 produced worldwide. As a result the trade prices have ACTUALLY INCREASED, a first I have known in ten years of retail pricing trends of lasers
GREEN lasers prices have dropped but will NEVER reach the price points of reds as there simply isn't a market for greens to the scale of reds. Green offers no advantage in dvds players etc and the predominant use for green lasers is still PRESENTATION lasers as they have a huge advantage over red in terms of brightness. This is fine but the worldwide market for the production of green lasers for any use is less than 1% of the production of red so you can see why red has became so cheap; simply a matter of volume.
BLUE lasers have now hit the market at **HUGE** prices and I predict that in the next 5 years because the of the MASS production of blue lasers for DVD mass storage products (BLU-RAY technology), after time their will be an overcapacity of the production of blue lasers which will mean they will become seiously available for presentation lasers , just like red I am going to GUESSTIMATE that a blue laser will cost less than $10 by 2010
Added by webmaster:
The blue laser used in Blu-Ray products is a directly-injected laser diode emitting a wavelength range of 405nm to 415nm. Blue handheld laser modules available at this time are DPSS (diode-pumped solid state), emitting a wavelength of 473nm.

Further I guesstimate that by 2008 you will have the Worlds first FULL COLOUR HANDHELD laser display (laser show), you will load the controls/images into it via a USB memory stick and you will be able to walk around witha **FULL COLOUR** laser show in your hand , it wont come cheap initially but when blues drop to a silly $10 price you will have a very cheap RGB system to create any colour. By 2015 full colour lasers shows will be that cheap they will be available to kids as toys for $100. the only thing that will keep them around that price will be that the Green diodes will not be mass produced so will be a lot more expensive than the blue or red diodes within the system .
An additional reason for higher prices of yellow, green and most blue lasers compared to red is:
Red laser pointers have a laser diode and optics, often as simple as a lens. Many lower cost red laser pointers have no more than a resistor for additional circuitry.
On the other hand, green, yellow and most blue laser pointers are of the more complex DPSS type. These have a higher power diode laser that typically has more involved circuitry than that of cheap red laser pointers. In addition, there is a laser rod or crystal pumped by the diode laser, laser mirrors to go with that, and a frequency doubling/tripling crystal and means to separate visible output from the infrared wavelength(s) of the laser crystal.
Do you manufacture or sell an LED flashlight, task light, utility light, or module of some kind? Want to see it tested by a real person, under real working conditions? Do you then want to see how your light did? If you have a sample available for this type of real-world, real-time testing, please contact me at ledmuseum@gmail.com.
