It’s apparent that the author is a statistics geek.
I like the way he writes and writes facts. It is
always such a pleasure to read posts made by real professionals.

I am fed up with that no-name, ghostwritten articles.
That is the reason it was so wonderful to look at a compelling piece.

Hello, Tero.

Since recently I have been developing a power source for a powerful laser that will be used for medical purposes. I need a power supply with an output power of 1.5 kW. I see you have 3 phases on one board, and the current is stabilized by the current sensor, so I understand? What recommendations can you have for my development, can you recommend what literature to read. could you contact me by mail and there I will tell you in detail about the problems that have arisen during the design. makaresy@gmail.com

I am intrigued with the 50A laser diode driver, and its stackable configuration for higher output current.

Is this a commercially available product?
Any further info you can provide is much appreciated.

Best regards,
Charles

Yes, a local company called Cavitar Ltd develops a laser diode based device that can “print” from metal powder.

Hi Tero.

Since you have working closer to laser industry, any laser diode have power enough to do “additive manufacturing” (3d metal printing)?

Good to see applications & projects emerge :)

I’m not expert of defense tech and how they use lasers but I guess they’re mostly serve compact & coherent light sources, not something that directly tries to do any damage. When laser was invented, it was supposed to be a “death ray” but it proved to be lousy death ray and it turned out to be more like a “life ray”.

Fantastic! As one immediately thinks of precision spark erosion equipment. For example, I need this. If that is with a spherical universal electrode, which has many fine holes for the salt solution, I can build my own EDM system soon. Something else: Today defense should look different than in the past! Laser-defense systems bring suffering, and no peace. (I don’t want to annoy).
Best Regards

Nx50 is best for driving high power diode laser. Such high power laser are used in myriad of applications in medical, industrial, material processing, defense and communication areas.

There is new development of deploying laser diodes even as light source of car headlights: http://www.computerworld.com/s/article/9247359/BMW_s_new_i8_is_the_first_production_car_with_laser_headlights

What are the applications?
