Viasho 4W 532nm OEM laser module

[sbk]

Have to sell this head, brand new, never used other than for testing purposes.

I bought two of these modules last year. Later I bought a proper power meter with enough range, and noticed one head did only 3.3W (the other was fine) so I returned it back to factory, and they sent me a new unit BUT with a brand new shape which is way higher than the one I previously had and designed the projector for (87mm, and I have a max of 83mm inside projector) so unfortunately I have to sell it.

I measured a bit over 4W, stable after warmup, will post pictures later of my Coherent Fieldmaster measuring output.

Some measured specs :

- Power stability over 20min at full power : min 4.01W (cold start), max 4.17W @25°C. Stabilized at 4.10W.
- Beam diameter @ aperture : around 3.5 mm
- Beam diameter @ 5.00 meters : 9-9.5 mm, almost a perfect circle
- Divergence full angle : 1.1 - 1.2 mrad

This is the same model Viasho sells on eBay here for 4099$, but with the OEM driver instead of lab one, much easier to integrate.

Comes with the related 5V/12V power supply.

Price : 3600 USD or 2930€ shipped anywhere in the world.

Of course if it's sells here, something will go on the janitor's account.

You can see the OEM driver on top of the power supply :



After a few minutes warmup, the beast stays a bit higher than 4W.



Feel free to ask whatever about this laser. Oh and the warranty from factory period will run till 19 July 2013...

I finally found some time to do measurements on this laser, and results are quite good :

- Power stability over 20min at full power : min 4.01W (cold start), max 4.17W @25°C. Stabilized at 4.10W.
- Beam diameter @ aperture : 3.5 mm
- Beam diameter @ 5.00 meters : 9-9.5 mm, almost a perfect circle
- Divergence full angle : 1.1 - 1.2 mrad

Bump

Open to reasonnable offers too...

Well, that 666 number of views of the thread is a sign to tell me that I unfortunately have to decrease a bit the price, lets say 3400$ or 2660€, always shipping included.

If it's not sold in a few weeks, I will let it to the highest bidder or on eBay, so don't hesitate to send me offers by PM...

If I had the cash, I would have it. Could I trade the wife?

Depends, how is she looks like? Haha, I hope for you she didn't read the forum

Bump!
The last one before eBay, don't miss an opportunity to have a brand new, under warranty, with a very good beam quality 4W 532nm for only 2500€ !

Hi,
Does this include a driver? Is this suitable for pumping a Ti:Sapphire CW laser? Is it polarized? Thanks, Phil

Hi, of course it has the full OEM driver included, with analog or TTL modulation, and the 5V/12V power supply. Without display however.
Modulation input is located on a 15-pole DSub connector, so you can adjust power with an external voltage, or just move the switch of the driver to full power.
Polarization is >100:1, I haven't measured it exactly but I can if you want, with a PBS cube.

I don't know anything about how to pump a Ti:Sapphire laser, all I know is that a 532nm laser beam is commonly used...
