Home made blue dpss laser

The coatings are all wrong. You could salvage the pump diode and the lenses, but that's about it.

Like Mike said, it's expensive...

well you would not have to get the pump diode but like Rob said at the top of the page you would need to get the right coatings on the crystals, so if you had an old greenie with say 1 watt pump diode and if you got the correct coated crystals needed i surpose you could get around 25/35 mw of blue all depending what wavelength you wanted

[allthatwhichis]

Could you use the power supply with the same power diode? Would it be worth converting the 150mW LE I have? Or are the coated optics prices more than a 30mW blue? I saw the thread and the idea popped in my head.

[buffo]

By the time you bought the two crystals you needed, and the second TEC, and re-tooled the interior to mount everything, and went through the painful alignment procedure...

Yeah, I think you'd be better off just buying a new dpss blue unit. If you don't like the 150 mw green, E-bay it. I don't think there's much potential to save $$$ by doing it yourself (at that low power level anyway), and there is a significant chance that it won't work once you assemble it.

Something like 350 for one bibo and the yag I am not sure of yet. Diode would need to be 2 to 4 watts of 808nm or a little higher. I have no data on the damage threshold. Something like 3 to 4 hundred for a diode in a C mount package at 5 watts w/ fast axis correction lense. Now you see where this is going......expensive.

Yip you are correct...

getting expensive.....!!!

Perhaps i should wait for the Laser TV System ??? To arrive on the market & then remove the RGB Lasers & have Fun...

I can confirm the crystal kits are expensive.
I got a quote for the Castech kit - Nd:YAG, BiBO & o/p coupler - £279 GBP
I ended up buying a >20mW blue DPSS for £180 - A bit of tweaking later it is doing 100mW (& still has some margin left on the pump diode rating)

nice what 20mw blue did you buy?

[Lampy]

How do you know how much the crystals can take? Learn from others mistakes or just see what you dare get away with? Is there some formula for working it out without blowin stuff up? Sounds scary.

Hi robin

Cheers for your reply....

But i already have a Blue Dpss laser that is outputing 98mw.

& it is working perfectly.

But i would like to know if it would be safe to up the 808nm pump diode

to get more power.

Hi Adam

Why are the coatings all wrong ?

The Blue 100 mw Dpss laser that i have work`s perfectly

All i want to do is replace the pump diode with a higher power one.

Only if the optic`s will not be damaged
