  • Similar to a led, except it emits laser light
  • Mainly useful for defined light sources (things like fiber optic messaging, optical data storage etc
  • Can also be used for Laser Engraving , if enough power Laser Cutting , and produce Bubblegrams

To Do

  • Look up what wavelenght is good for what etc
  • Look up control circuitry (how to make fast pulses, variable strength etc)
  • Use this info to develop a Open Source Laser Diode Toolhead


  • 60W laser diode cuts steel foil. YT potential SME. - [1]
  • 500W for $2k - not replicable sourcing - [2]
  • 10W for $90 each in MOQ of 10 - just the diode itself.
  • 500W hair removal wide beam - $1300 - [3]
  • 60W Coherent diode - [4]
  • 500W for $400? - Maybe each bar is that much. Stack is made of multiple bars. How are these stacked together? [5]. Can be used for Diode Pumped Solid State Lasers. Has water cooling. Needs power supply.

How It Works

  • Video explaining fiber coupled laser diode. Potential SME who knows how to design a laser diode and has access to equipment to build one. - [6]

How It Is Manufactured

  • How laser diode bars are made - corporate promo video - [7]
  • About structure of laser diodes, bars, stacks - [8]

How To Couple a Diode Bar to a Fiber

  • Master's thesis on how to couple a divergent bar source to a fiber - [9]
