Novalux protera (DPSS 488nm) lasers for sale.

Ok so here’s a short summery on these lasers. Based on what I have found

The protera laser heads were designed and built by Novalux back in 2002 and 3

The lasers are VERY temperature sensitive and they had the company Vuemetrix build a computer controlled driver to run them. An engineer at Vuemetrix ( he told me he was the one who wrote the program for them many years back) told me over the phone when I tried to get a copy of the software.

It never worked

some worked great exactly as designed however most either did not work or worked in a crippled state

He never figured out why.
(Unknown info)
Somewhere along the way Laser2000 Germany built a black brick style driver for them.
Each laser wants a different temperature in order to lase so each driver was tuned to a head and the drivers were labeled to match the head.
(Unknown info)

Somehow the heads and drivers got mixed up.

That is where I come in.
Junktronix sent me his heads and a breakout box so I could tune them.

There or 2 pots inside in charge of crystal Temperature (TEC on crystal) and main TEC.
(These do not affect diode current I’m Not Pot moding Like it was believed in my review)
Using a breakout box he sent me I Started at the coldest setting for the crystal tec and warmed it up until the laser flashed the brightest and I would write town the temperature that it was reading at the flash. Then I would to the best I could (remember these lasers were already crippled from the start) tune it stable(ish) at that temperature.

And finally now that I (Think) I fixed my power meter here is what you have all been waiting for






Now for the power.
Laser head 1 and 4 work the best and the brightest.
• laser 1 17mW peak ----Price $300
• laser 2 ( Coming soon )---- (to be determined)
• laser 3 ( Coming soon )----$150 (do to power drop this one will be the cheapest)
• laser 4 ( Coming soon )----(to be determined)



Here is the deal My Kenometer and lasercheck are saying 2 different things
It turned off before just a second before i was able to snap that picture but it said 7mW
_________________________________________________________________________
Now for the bad news They all drop in power over time some faster than others
This is after les than 4 minutes and laser head 3 dropped to almost nothing


I also have ones with broken TECs (wich means diode block is loose) that still emit IR. Maybe candidates for a DIY project

Edit: Here are some pics of the inside of the head. (These are from my old review.)




Power graphs to come soon

Here are some pics of the diode I extracted




here is bare diode

Re: Novalux protera lasers for sale.

What's your asking price ?

Re: Novalux protera lasers for sale.

this one I am working on now does not stabilize so its $200.

it starts out at maybe 5-7mW (bye eye) but fades to nothing after 5 minutes I'm still working on stabilizing it.

the diode block with crystal emits IR but no 488 but its possible with some tec work it may. That one is $75

The one requirement to whoever buys ether is if they take them apart they must post pics of it.

Re: Novalux protera lasers for sale.

If only I hadn't spent most of my money on other things. Oh well.

Re: Novalux protera lasers for sale.

Bump its ultra stable 1 mW or less on my laser driver which means the head is most likely fine.
maybe someone can run it via the computer driver compucycle has.
$100 for head $175 for head and driver.(not my driver the one that veries the current)
cable included with driver

Bump its dpss 488nm at at least 5mW for $175 Or best offer
I mean come on you cant beet that

Pm me asap.

How is the 488 produced?

Direct doubled from a VECSEL 976nm diode

Oh, neat.

If you'd be willing to wait for feebay to take off for me I'm definitely interested... sadly I only have $50 now...

No hurry. as soon as i sell this one i get another and I also will then buy my self a Kenometer :san:

Would you be interested in trades maybe?

No only because these lasers aren't mine and I'm splitting profit.

I'm sure people (including me!) would be more interested if you:
1. Take pictures of what the buyer is receiving.
2. Explain what the buyer needs to do in order to get this to work (is it plug and play?).
3. Post some verification of its output.

Just a suggestion!

OK here is an update I have 5 now in stock.
I have a coherent lasercheck and using that have tuned the heads all to above 5mW some as high as 10 with peaks of 20mW.
I bought a Kenometer pro to get some power-graphs of them but I have a problem. The lasercheck and Kenometer to not agree on there power.

When the lasercheck says 3mW the kenometer says 21 :thinking:

It also says my lasever 10 mW is 75 mW (Yes I'm zeroing the meter before hitting it with the laser. ) :gun:

Mabye the lasercheck doesn't pick up IR?
