Alice: I'm not sure who's laser (manufacturer) are needing replacement only after 6 months. I was an optical design enginner for a biomedical instrument manufacturer in Maryland. We had red diode lasers in service for years. These were top name, US made modules. Now I am owner of Creative Technology, a diode laser module distributor, and manufacturer. Even our imported red modules have been in service a long time ( a few years). Your information on lifetimes seems too short. Do you have any further info. on the model, manufacturer, etc?
