I bought a green laser module from this site
aliexpress.com/item/4000983430911.html?spm=a2g0o.productlist.0.0.d48a7d61EWSES6&algo_pvid=5466a630-252b-4159-90cf-d4350df92a60&algo_expid=5466a630-252b-4159-90cf-d4350df92a60-26&btsid=0be3769015977396861066047ed32c&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_
i removed www. since the forum doesn't allow me to post links
it look exactly like in the picture shown there. The retailer claim it give an output of 50 miliwatts. But to me it's kinda dim, more like a 10mw.
Upon closer inspect i realise when first turn on the beam is very bright, however the power drop almost instantly after less than 1 second. So i decide to put it in the fridge for a few minutes, take it out and this time, while chill it give a very bright, true 50mw light beam to me. But then of course, come mode hopping
I have tried 2 other module in the past also dpss green laser and this also occured. I know that these cheap modules behave like this are expected but i can't just throw money and buy dozen of them. Are there something can be done? I only need the module give me full output for 20 seconds or so, not terribly long so i'm thinking of changing to another heatsink that is more tight fit, or apply some thermal paste. If all fail i might just switch to blue/violet laser since with green i don't have much luck at all
