HeNe Lasers VS Diode Lasers: HeNe Laser Pros and Cons

Historically, Helium-Neon (HeNe) lasers were often the first choice for precision instrumentation, measurement setups and some spectroscopy applications. It was invented in 1960 and technologically it was one of the first lasers with extraordinary good parameters. The mechanical and optical design is quite simple (apart from sophisticated glasswork to make the tube itself) but the gas lasing medium and overall construction provide some intrinsic advantages. But also a number of disadv… Read More

Higher Power fs Fiber Lasers to Image Better, Deeper & Faster

Two-photon microscopy has become a key fluorescent imaging technique that enables in-vivo, non-invasive 3-dimensional imaging with sub-micron resolution in volume. Challenged by the wider variety of applications particularly in the field of neuroscience, two-photon microscopy has led to the conception of systems using new excitation techniques and innovative lase… Read More

Laser Source Requirements for Modern Laser Designator Systems

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. This determination is particularly challenging when enemy assets are camouflaged or hidden amongst civili… Read More

OEM Fiber Lasers for Industrial Laser Induced Breakdown Spectroscopy

Industrial laser induced breakdown spectroscopy typically involves the elemental analysis of various metals. In our previous application note titled “Laser Induced Breakdown Spectroscopy (LIBS) in Biomedical Applications,” we discussed the fundamentals of the technique, emphasizing the use of q-switched diode-pumped solid-state lasers as the excitation source. 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

QCLs & New Low-Cost IR Sensors Open Door for Many OEM Opportunities

Driving a vehicle at night or during foggy conditions can be tricky and dangerous, where poor visibility can cause undue stress or even an accident. These conditions make it more difficult to see upcoming potential obstacles, especially if that obstacle is a deer in a field or a pedestrian in dark clothing at night. However, thanks to newer, more efficient, and cost-effective advancements, we could see more widespread deployment of LIDAR-based automotive detection and warning… Read More

The Advantages and Disadvantages of Passive vs Active Q-Switching

Q-switching is the most effective method for producing high energy pulsed lasers.  While there are many different varieties of a q-switch, they all follow the same basic operating principle.  Q-switches temporarily increase the cavity losses so that the gain threshold is artificially high preventing the laser from emitting light.  This process allows the population inversion inside of the gain medium to grow until it becomes fully sa… Read More

Stable, Narrow Linewidth, CW DPSS Lasers for Precision Interferometry

Interferometry is one of the most widely used precision measurement techniques known to humankind. The precision provided by interferometers has enabled countless scientific discoveries and breakthroughs. These discoveries range from the Michelson and Morley Experiment in 1887, which led to the discovery that electromagnetic waves could propagate through the vacuum of space without needing an “aether” to detecting gravitational waves in 2015 by the Laser Interferometer Gravitational-Wave Observato… Read More
