do chinese ps2 laser knockoffs exist?

**Crimsondreams** · 08-06-2006,09:35 PM

it cant be that hard for someone to duplicate the design of the ps2 laser and mass produce it in china can it? If you think about it we have come so far regarding modchips that can boot anything but noone has bothered to try to replicate the ps2 laser? I wonder why? or maybe does someone know of anyone attempting this?

I thought they did? Most sites that sell "new" lasers usually say something about not being cheap knockoffs from China so they are out there.

In Bangkok's Saphanlek wich is the main market here for ps2, one shop showed me a presumed ps2 laser copy.
I did no see the difference but a month ago I received a ps2 V9 for modding wich had a KHS-400R laser and it had a plastic frame.

That made me thinking about producing the lasers and the first thing is to find a laser photodiode array wich is compatible with the Sony RF chip.
Then after finding sources for parts and a precision molder there is an investment in optical precision instruments for calibrating the lasers.

chinese makes tons of red laser pickup units, and i don't see why not the ps2 parts; however, i don't think the market is big enough to get the quality lasers from china

my friend's slim ps2 has a made in china laser assembly & works very well

The problem is finding good replacement lasers for the old thick playstations and for a reasonable price.
If copy lasers are produced in China why has Divineo China no stock of brandnew (copy) lasers and offers only refurbished original Sony lasers for 54 USD ?.

Will the referb lasers last as long as a brand new one? Just wondering cause its even cheaper.

I would like to get a source for the laser diode only, i can exchange them
on the flat ribbon cable, no broblem at all.

I know they exist somewhere to buy, please help!

Refurbished is repaired and if:
1 the coils are replaced, you receive a secondhand laser with a (very) limited lifetime.
2 the laserdiode is replaced, it can be new maybe and new ps2 laserdiode are very rare on the market.

There were some chinese sellers who offer laserdiodes but not new and moq is 100 pcs, and one company listed new laserdiode for 35 UDS and it was sold out in a short time.

Changing the laserdiode is not easy, the laser pcb is very sensitive for heat, the laserpcb is glued and with re-using it curls up and without instruments for adjusting the laserdiode position (angle) you have to get lucky to get it to work.

Some did work and some not, gave strong light but no focus.

There is guide marks on the part which holds the laser diode. It's not that hard to place it on the right position. The worst thing to adjust is the lens position as you have to bend the metalic body of the lens to adjust it to the new position of the laser diode ... lol

So since you can bend the lens to compensate, it's not really THAT critical... Yes, having tools for helping with the position of the laser saves you a lot of time but still are not needed if you know what to do to compensate the miss-alignment on the laser diode

Now a wonderful tool to have would be a tool to measure the laser output power versus power consumption, which would allow me to discard defective laser diodes without having to mount them on the laser units to test them...
