3watt X Laser (China)

[JD3]

A friend of mine was just given one of these ask "payment" for a debt he was owed by someone.

The green diode is out. Anyone have any experience with this laser? I offered to lend a hand to fix it /replace the green

Thanks guys

Sorry, it appears the forum goblins deleted several lines of your post making it hard to understand what your actually on about.

Can you be more specific ?

Does anyone have a 3 watt china xlaser.
If so. What diodes are inside it. I need a new green one.

Ah, so its a 3W projector with a failed DPSS 532nm green right?

The green is more complicated than you think, being diode pumped 808nm Infa-red converted to 532nm via a "black magic" crystal set. The IR pump diode may have failed and realignment and calibration is not for the faint hearted...

Post some pics of the green laser module.

Correct. I was assuming I would be able to replace the assembly rather than fixing a component of the module.

I asked him for some pics. Still waiting for them.

Replacing the module is easier but you need to know a few key parameters such as:

• beam height from deck, typically 24.8 or 29mm
• Analog or TTL modulation?
• Driver supply voltage (5v, 12v or mains)
• Physical space restrictions for module and driver

To name a few...

Could he just "hot swap" this out and be good?

need that much?

I don't have access to the laser so I'm not sure. The actual module that is in there is a 1watt. But he found that 500mw and wanted to know if it would work

As long as it physically fits, you can swap any module in there. If the beam height is different, might need to add an aluminum spacer. In my experience dhom's come a bit overpowered so the 500mW may end up being more, though can't count on that being for sure. Knowing if the laser is analog or ttl would help you make the decision as to what to buy, but upgrading to analog is usually a good thing anyhow.

That being said, if the previous module was a 1W, probably would get the best colour balance if you replaced it with another 1W, but could always turn down the red / blue to match a smaller green if need be, but you'd end up with a lower powered projector in the end. The price difference should be all that much between the 500mW and the 1W
