Greetings to all


Willing to sell these or trade for them. Make an offer.

I have 7 sets of coherent laser diodes with power supplies with objective lenses that were pulled from CTP machines (computer to plate) that have been laying around for some time now.

4 pcs 80 watt and 3 pcs 60 watt. They all come with their respective power supply, which are water cooled, same as the diodes.

All of them I have pulled from Agfa CTP’s.

4 sets I am keeping to myself for all kinds of fun project ahead but 3 I’m willing to part with.

The CTP’s are rated for over a million plates produced over it’s lifetime without replacing the optical bed that houses the diode, GLV (grating light valve) and all the magnification and focusing lens assemblies. The machines produced barely over 220K plates over their whole lifetime in operation and haven't been pushed beyond 45 amps to maintain exposure. So the laser diodes have over ¾ of their life span intact.




- Let us get into a more interesting side now, some specs:

The power supplies as I mentioned are water cooled, made by a US company Tri Source Inc. (from what I know, dissolved now as of 2016)

The supply runs of 180-265 V AC at 47-63 Hz and outputs CC up to 120 amps at 2.2V. Both diodes and the supply have a grounded anode design.

Fully adjustable from 1-120 amps. Controlled by an analog input with 1k impedance that can accept both CC and CV signals. Since it’s 1000 ohms, it doesn’t matter if it’s current or voltage- it’s balances out equally. 0-6V or 0-6mA to get full 120 amps out. Additionally, there is current monitoring output from an op-amp voltage follower circuit through a 1K resistor.

The diodes run at 67 amps MAX for 60 watt and 85 amps max for 80 watt. No more than 2.2 volt should ever go across the cathode and anode. All diodes output 830nm wavelength at 20.0 °C intended cooling work temp. The temperature should not go over 22°C during operation.

Diode with power supply and GLV were originally cooled in the CTP with a portable vapor phase change chiller running on R134A. Optimum flow rate 4.5 l/m at 1-1.4 bar.





-If interested, I also have FT-110 series flow rate sensors made by Gems sensors and Controls that came from the same optics bed of the machine, to shut down the laser if cooling flow stops. (sold for separate price)



-The setup is plug and play pretty much; you get everything necessary to power on the laser to full power out of the box.



The things required from your side are of course:

  • Electrical experience to keep you alive and well
  • Laser training and safety precautions
  • Protective eyewear capable of blocking near IR with good OD rating
  • Your own chiller for the laser set
I will be selling these from our company, so the price will also have VAT added. If you buy from a EU company with valid EU VAT number, then the VAT is deducted.


The 60 watt laser will be 2000 EUR + EE VAT 20% and the 80 watt will be 2500 EUR + EE VAT 20%

Please ask any question or express any interest and we can always trade, if you have something interesting ;)

It isn't common to see these sold with a power supply.
I have a 50W FAP-I without a supply myself already.
Good luck with your sale.

I tried to make the offer as simple as possible with pretty much a plug and play system. Price is not final, make an offer and we'll work something out. Always opened to negotiations.
