A brief look at a twenty different diodes, their symbol variations, and a basic description. And yes, we're looking at tubes ...

The basis of a solid-state diode laser is, of course, the diode. Laser diodes can have different emission wavelength—most of them have between 405 nm to 808 nm. The diodes usually have TO3, TO5, TO9, ...

Where there is power there is heat, and where there is heat there is often a need to sense temperature (the most widely sensed physical variable). What we call temperature is our measurement of a ...

Comparison of a 5W laser, 10W, and 20W diode laser. All these machines have their pros and their cons, but this is a quick ...

The history of the diode is a fun one as it’s rife with accidental discoveries, sometimes having to wait decades for a use for what was found. Two examples of that are our first two topics: thermionic ...
