Thumbs up Hello

Hello to all,
I'm Phill from Newcastle Upon Tyne, England.
Any Advice Would be greatly appreciated, Only just discovered lasers as a hobby,
This is my first attempt at a build using an M140 diode, a driver, a heatsink & an 18650 battery, seems to work ok, but I'm concerned about over heating, it gets very hot quite quickly. I don't let it run for more then 30 seconds.

Hello, and welcome to the forum
Do you have any safety goggles ?
Are you using heatsink for the driver
and for the laser diode ?

Hello & thanks,
I have goggles, thanks, safety first,
I am looking for a host for this project,
& a heatsink for the driver,
does a good thermal paste make a difference?

Glad you have safety goggles
Here is a list of the host + diode heatsink kits:
Laser Host Kits : Cajunlasers Store
Here is a heatsink for your driver: (it has a thermal sticker so you dont have to use thermal paste)
Mini copper heat sink for laser driver circuit [CPRHTSK] - $1.99 : Cajunlasers Store

EDIT: I have some hosts and heatsinks for sale also pm me if you are interested

Jim
