During any manufacturing process, there is some statistical variation in the finished product. Resistor manufacturing is no different, and for many years traditional bulk and chip resistors have been tested and sorted into bins and labeled based upon these tolerances. Board mount chip resistors are also similarly tolerance using a numerical code instead of a color code, but the end result is the same. However, this is not feasible in larger format thick-film or thin-film intergraded circuits which require initial calibration, such as operational amplifiers, voltage dividers, and oscillators, where the resistors are one small detail in a much more complex arc… Read More
In our last blog post, “Laser Amplification for Power Scaling,” we discussed how an optical amplifier can be used to increase the power of a seed laser while maintaining its performance characteristics. The same basic principle can be applied to a laser itself, with a method known as injection seeding. In this case, a single frequency laser is sent into the laser cavity therefore selectively reducing the gain threshold at that specific frequency as shown in the fig… Read More
Modern lasers come in a seemingly endless variety ranging from diode lasers as small as a grain of rice to CO2 lasers the size of a refrigerator. The one thing that all of these lasers have in common is that they contain the three basic components of a laser: gain medium, resonator, and excitation source. If any of these three components are missing, achieving threshold and starting the lasing process would be impossible. In this blog post, we will examine what happens when the resonator is removed from this equation, resulting in an optical amplifi… Read More
