why do you need a laser module?
Well those tiny laser diode also spec-ed at 150mW and 533nm green laser.
can you not use those tiny diode laser instead of the large moduled one?
Am I missing something?
Because those units you linked to have all the driver/cooling etc parts as well
are you saying inside that module there is the same TO 3 terminated laser diode ?
That linked module appears to be overengineered with a too massive heat sink for only 150mW. Price seems surprisingly low too for that construction...
Unless there is a difference in chinese milliwatts and real milliwatts. Rethinking, ... they are all chinese. Never got that clear comparing with :

With driver circuitry and heat sink barrel. And they do work.
maybe not the identical one but one of similar type :)
probably designed for long periods of use / hi duty cycle
