Blue Laser Pointers

[DayOfShadows]

Hey, ive been talking to a blue laser manufacturer and getting quotes on pen style lasers. I was wondering if 375 is a good deal for 5 mW? They said the minimum order was 5 and would give a even greater discount if i order 10 +.Is there any interest in this or its the dog already beat?

im not sure exactly how much 5mw blues go for but do get in touch with scopeguy20 im sure he can get you a >5mw blue cheaper than $375.

You can get a Laser-Wave >50mw blue module for just around $580US + postage. Not all that useful, since you are looking at pointers, but just as a benchmark. TEC cooled on diode AND crystals, Analog modulation etc.

why are blue so much more expansive then green or red?

 

[rangedunits]

Effectiveness of crystal is low.

And the LBO itself is pricey. That's why the prices aren't linear.

Portable lasers will always be more than labby lasers. That is an ok price. I would rather get a 5mW 473nm CNI build from Dragonlasers for $400.

Personally I'm gonna hold on a blue pointer for a few years. Wait another 2 years and the price may drop by 25-35%. I remember in the 90's green pointers were hundreds for just 5mW. Breakthroughs in crystal growing or crystal efficiency will bring the price down (eventually). :-/

And blue laser diodes actually exist now, and should eventually be mass produced for displays/projectors/TVs and such.

the blue laser price higher than other lasers because the blue doubling crystals had very low conversion efficiency. example (2wLD+3*3*2(NDYAG)+2*2*10LBO get about 50-100mw 473nm ) the cost of crystals (LBO,NDYAG,LENSE)Total about $130. So I think the cost also very cheap.

but If only need 5mw blue, I think can use by other doubling material. the BIBO crystals had higher conversion efficiency than LBO. get assemble like green laserDPM you could get about 10mw blue laser.
If anybody be intersting in crystals questions please disscuse on fourm.

BIBO is more efficient but is also far more expensive.

 

[lasertec]

BIBO price cheaper than LBO, because BIBO only need very small to get higher output power.
but BIBO coated would be very difficult, if had large quantity I sure the price would be reduce quickly
