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

Continuing with our recent theme of application for laser diode bars and stacks, in this post we will take a look at laser cladding.  If you haven’t already read our previous post titled “Understanding Laser Diode Arrays,” or have a basic understanding of laser diode bars and stacks we’d highly recommend you check out that post before reading … Read More

By combining TOF lidar at 1.5 micros with an InGaAs camera, you can produce a hypercube or “point cloud” containing a three-dimensional image of the target. This technique known as active night vision laser imaging, is discussed in this post, as well as which laser is best for this ap… Read More

At RPMC we offer one of the widest ranges of laser diodes on the market, and if you have been following us for some time now, we often mention that we offer both single emitters and arrays (bars).  In this blog post we are going to take a look at exactly what we mean when we talk about diode bars, but in order to do that, we need to first take a small detour and talk about the role of the ridge waveguide in laser diodes i… Read More
