Powering on a laser diode that exceeds PSU max current
I have a laser diode that I want to test (just seeing if it turns on). However, the threshold current is past the 10A that my bench power supply can supply, hence I can't generate any light. How can I ...

Feedback from a 100 W laser power supply
I built a 100 W laser cutter from scratch using a controller from a small laser cutter I had
before (Open Builds Blackbox 4x).
It worked with no problems, but I'm going from a 7 W laser to a 100 W ...

Build plans for a PSU 13.56 MHz 300 W - 1000 W with adjustable voltage between 200 V - 500 V
This is a kind of continuation of a previous thread Howto: RF HV power supply (13,56 MHz, ~30 kV - 50 kV, 1 kW - 3 kW)
I made the assumption that the voltage for exciting plasma with DC co-relates to ...

85W laser array driver circuit
I have an OSRAM 85W 450nnm laser array.
It's essentially a large 'chip' with 24 integrated laser diodes (break it down they're approx 3.5W diodes each.) The Chinese source I purchased it from also ...

Is an exhausted PSU safe to use for an FPGA? [closed]
For a project I will have 4 stepper motors,a laser module and few modules attached to the FPGA.
I need around 10 amps.
Clearly the FPGA can't provide enough power for all the modules.
I think to use ...

CAM 5 LASER CUTTER : needing to change the laser tube [closed]
My boss and I discovered that one of the laser tube needs to be changed, and when we figured which one needed it, I told him not to touch the red wire, that there may still be power in it. Well he did,...
