Default New blue 450nm laser

Hello, this is my first post in lpf. Recently i have been in china, and I bought there a blue laser. I've seen that the laser burns good almost everything but it looks to be like a bit unfocused. I took the lenses out and saw that the diode was in good condition and the shape of the light emitted is almost a rectangle like all the 450nm laser but it have's like a lines in one of the extremes of the beam. Anyone knows if there's a problem with the diode or lenses?

Thanks and sorry for my bad english, I'm from Spain.
Here some images:

This image is when the laser have's low battery and it can be seen the beam better, don't worry about those black lines, they are the result of focusing the laser into my phone's camera:

Hello LaserTaco, thanks for your comment. I'm not sure about that because when I take out the lenses the beam looks like this: (some difuse lines in one of the extremes of the beam) and it's direct diode.

And I've just broken my red laser... The only good part of thise is that I've picked the lenses of the red laser but I didn't know how to change it with my 450nm laser lenses. This is where de lenses of the blue laser are. How to remove it?

Don't show enough pictures for us to see how to remove it. However the lens may not be the same size as the other one.

Hello Pman, so, I will have to buy a new lens? if so, what lens do you recommend for a 450nm laser?
Thanks. If I couldn't repair the laser I will sell it, if someone who want's to repair it I will sell it to he.

hi,
Play with the less if you can first ,go slow and see if the lens changes the divergence. Man and Red do a lot of divergence testing.

Yep that is a typical raw and after single element lens output of the Osram diodes. The Nichia 445's have a similar which makes a box reflection where the Osram diodes are more triangular.

Hi, thanks to all of you. I think I would sell it and buy a new one. I don't have time to buy my own lasers but it's a thing that I want to learn and maybe in a future I will do it. It's possible to calculate aproximatly the mW of one laser without any LPM, I know that it's so difficult and the accuracy would be so bad but I don't have a LPM and now I can't buy it.

It's possible - but not with any degree of meaningful accuracy. At least not if you're DIYing it at home - maybe if you had a lab with some sensitive instrumentation - in which case you'd just get an LPM.

You can send it to one of the members on here that has an LPM if you like.
