YELLOW LASER POINTER 593.5nm

Yellow Laser Pointer ! Finally Here !!

( If your Looking for Blue Laser pointer Go HERE )

After stagnation of innovation in the Handheld Laser Pointer Market for some years , it looks like we now have a couple of years of vast growth and innovation .The last five years have seen prices of the amazing little RED Laser pointer at under ?5 ..at that time hand held Green Laser Pointer were entering the market at almost ?1000 each but as production increased some four years on we now sell them for ?59 . We are delighted to announce the release in September 2004 of (Yellow 593.5 nm) YELLOW Laser Pointer for ?199.However during 2008 prices increased to ?249 due to low sales worldwide and no other markets for yellow diodes to help increase volume

These Yellow Laser Pointer are fully UK legal as < 1mW versions and will be ideal for large Screen presentations as the Brightness of the dot is more perceptible to the eye than red lasers . Purchase of this Yellow Laser pointer ensure EXCLUSIVITY , as these are one of the first deliveries of Yellow Laser pointer in existence anywhere in the world , so if you need your presentation to be VERY SPECIAL , very different and VERY remembered you know what to buy !! Yellow !

 

General Use UK legal < 1mW Yellow Laser pointer ?249 Free Shipping can be bought Here

 

Blue hand held laser Pointer (473nm) are available for special order but as the price is very prohibitive to the average user , at ?1000 per unit we cant Imagine why anybody would want want one for presentation use, however if you have a Scientific or Forensic reason for a hand held Blue laser please do contact us for us to raise a Special Order and have a Handheld Blue Laser pointer specially manufactured for you

SO WHY ?? Is yellow treble the price of a Green Laser

In a 593.5nm yellow DPSS laser (pointer or larger size), there''s a BIG infrared laser diode that generates laser light at 808nm, this is fired into a crystal containing the rare-earth element neodymium . This crystal takes the 808nm infrared laser light and lases at 1,064 and 1,342nm (yes, deeper in the infrared!). This laser light comes out of the NdYV04 (neodymium yttrium vanadium oxide) crystal and is then shot into a second crystal (containing potassium, titanium, & phosphorus, usually called KTP) that roughly doubles the frequency to 593.5nm - the bright orangish yellow color you see. This light is then collimated (focused) by a lens and emerges out the laser''s business end . Just before the lens, there''s a filter that removes any stray IR (infrared) rays from the pump diode and the neodymium crystal. You don''t want that stuff in your yellow beam, trust me. :-)

This is why yellow diode lasers are so much more expensive than red ones. Lots of itty bitty parts, and they all need to be very carefully aligned by hand. If the polarisation is off , one or both crystals need to be turned.
With red diode lasers, you just slap in the diode and slap a lens in front of it.

Remember the price brings exclusivity !!

Fully UK legal < 1mW these lasers emit a light far Brighter than Red Laser .
