Replace laser diode –
Hey, I've got a bunch of dead lasers around and got 32 of the laser diodes. I work with fine SMT parts so I have the experience, but all I need is a visual tutorial once.
Also would like to know if this is how the diode is removed:
1) Desolder flex PCB from diode
2) Desolder top and bottom of diode from laser
3) Resolder new diode to laser and then flex PCB
That tutorial is for replacing the coil loop, the laser diode is the one in red in this pic.
it shows how to replace laser coils.

i always use 2 plastic piece cut from old negative photo film. then insert the films into the edge that holds the soft silicon stuff to isolate the silicon. then unscrew the top black screw and lift the whole coil assembly. remove the coil with the films still on it and re-assemble the coil. finally slightly remove the films.
That's good information, but not very helpful. I need to replace the laser diode on a laser.
I'm afraid I can't offer any concrete details, but I've been told that with typical diode designs it's nearly impossible to do it without a microscope for doing proper rotational alignment of the diode package - there are actually multiple beams, and they're meant to be oriented in a certain way with reference to the CD/DVD channel. I'm not sure that the PS2 lasers use a three-beam design, but it seems likely.
