Basics
- 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
Examples
- 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]
