and these are inside it , i was used boost driver 230mA with diode PLTB450 :

I like the host. What kind of duty cycle do you get?

Hi Thanhtung:

I think Gazen was asking about the time that the laser can safely remain running without danger of overheating, and how soon it can be turned on after it’s been shut down. I hope that this is helpful. Thanks and Take Care.

That's a cute little build. I see why you set it so low and run it for only a minute. You ought to try using copper modules instead of the nickel plated brass ones. They conduct heat much more efficiently and heat up far slower. I keep the brass ones around for some people who don't want the expense of copper, but they are totally worth it.

thanks, i will use copper in the next time because it conduct heat is better like you said:wave:
