...of the presence of astigmatism (see Diodes vs. HeNe). The output power specified is the maximum power value of the laser light after the beam exits the laser housing; in other words, power is rated after passing through (but not before) any optics. Values stated are typically within +/-10%. The light...

A ballast resistor is a mechanism placed in series with a HeNe gas laser anode. The unit works to promote a stable electrical discharge and to prevent the laser from oscillating. The rating of the ballast resistor must be high enough to stop the oscillation, yet low enough to prevent unnecessary...
