405nm vs 445nm comparison

Posted on April 29, 2011 by gizmo

I’ve been a bit disappointed by the 445 nm diode so far. It’s not really burning as well as the 405nm diode. So I decided to put down some estimates to see what is happening. I was unable to focus … Continue reading →

445nm 1 Watt monster diode

Posted on April 27, 2011 by gizmo

The 445nm diode came in and I’ve hooked it up to the CNC. This diode is a multi-mode laser diode. This means that the dot will not be nice and round as with the 405nm diode, but it has some … Continue reading →

Stanham driver

Posted on April 25, 2011 by gizmo

To run a CNC laser you’ll need a laser diode driver (current source) that can be modulated. I wanted a driver that can be modulated with an analog voltage as well in case I want to give EMC control over … Continue reading →

Laser530 paper stencil cutting

Posted on April 20, 2011 by gizmo

I finally received the BDR-S06J sleds and extracted the diodes from them. These diodes emit light at a wavelength of 405nm and go up to at least 500mA, where they put out about 600mWatts of power! That’s not bad. To … Continue reading →
