Combat zones can be extremely chaotic. With a massive influx of sensory input, implementing clear communication, rugged tools, and reliable instrumentation is key to a successful mission. One of the most challenging tasks in any aerial combat situation is determining which assets on the ground to target and which ones to avoid. Because of this challenge, a practice, commonly referred to as “painting the target,” was developed and has been successfully deployed for many years, allowing ground forces to identify and designate targets for successful engagement by aeria… Read More
A significant and well-recognized difference between lasers and conventional, incoherent light sources, is the ability to concentrate laser emission in short pulses, with durations going down to a few femtoseconds, containing potentially only a few optical cycles. Technically, you can drive an incoherent LED source using current pulses. However, each pulse would have a maximum power (i.e. a peak power) equal to the average power of the same device if a conti… Read More
In that blog post we cited NATO standard STANAG 3733, which required that the laser beam have a divergence small enough so that 90% of its energy is on target 95% of the time assuming a 2.3 x 2.3 m target. We went on to explain that most laser designators are designed to be used at distances up to 5 km. Therefore, one of the most critical factors when choosing a laser source is the beam d… Read More
Spectroscopy is a class of analysis methods meant for chemical species identification and concentration measurement, based on emission spectra detection, if irradiated by an adequate light source. Fluorescence-based spectroscopy is one of the oldest spectroscopic techniques. This technique utilizes electron-photon interactions and relies on the absorption of high-energy photons and the subsequent emission of lower-energy, longer-wavelength fluorescence photons, with the energy difference associated with vibrationa… Read More
In actively Q-switched lasers, the user controls the pulsed laser output, so that no laser pulse emission occurs without providing a proper input signal, aka “the trigger”. Due to the trigger signal propagation through the interface electronics, the Q-switch driver chain, and the laser resonator build-up time, a time delay (Td) is present between the externally-supplied trigger signal and the actual laser pulse emitted by the laser source. The Td can show fluctuations if any electronics or optics involved in the pulse generation process have a functional varianc… Read More

In this blog post, we are going to explore the possibility of utilizing nanosecond pulsed fiber lasers as the excitation source. We will also discuss the pros and cons of that approach, specifically for the characterization of metals and metal… Read More
The popularity of laser induced breakdown spectroscopy (LIBS) has been rapidly growing since its introduction in the 1960s, and is now used in industrial, military, scientific, and medical applications. Nowadays LIBS is rapidly becoming an indispensable tool for elemental analysis and is generally viewed as a complementary technique to other elemental methods such as mass spectrometry. Within the medical field, LIBS can be used for analyzing hard/calcified tissues, soft tissues, biomedical specimens; as well as disease detection and even during laser-guided surgery. In this a… Read More
Injection molding is a widely used process for rapidly mass-producing low cost highly uniform mechanical parts. On a cursory level, it is a relatively straight forward process by which molten material (metal, glass, polymer, etc.) is injected into a hollowed-out cavity, cooled down to solidify, and then ejected. This results in the material being permanently shaped to the internal cavity of the mold. This process has been around for hundreds if not thousands of years with the original molds being made out of clay and then broken apart to reveal the fini… Read More
