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

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

Critical Laser Source Requirements for Laser Target Designation

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

Peak Power and Average Power in ns and Sub-ns Lasers

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 continuous bias were applied. Only laser cavities can concentrate the stored energy within active materials in such a way to achieve peak powers orders of magnitude higher than their ave… Read More

Why is Polarization Switching Unsuitable for Interferometry?

A common problem for HeNe laser customers is the issue of polarization switching, which is the sudden change of the polarization of different modes, especially in shorter tubes, which can be particularly detrimental when operating frequency stabilized HeNe laser tubes. This phenomenon is sometimes referred to as ‘mode hopping.’ However, this is not accurate. While somewhat similar to polarization switching, mode hopping involves the laser’s operation on a single resonator mode, which suddenly switches to another mode, causing the optical power to switch over to this… Read More

Raman Spectroscopy: Why Are Picosecond Pulses Superior to Femtosecond?

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.

Key Laser Requirements for Bathymetric and Topographic LiDAR

Shortly after the invention of the first laser, a relevant application enabled by the availability of coherent light, called time-of-flight, emerged. ToF is the precise measurement of the round-trip time of a laser pulse from the source to the target object and back again, allowing you to determine the distance or the velocity of the target. By collecting the back-reflected (or back-scattered) radiation of a short pulse, initially directed to a remote target, it is possible to determine the exact position of said target, provided that the time interval between the outgoing pulse and the corresponding echo is precisely… Read More

Why is a Low Jitter Feature Important in Actively Q-switched DPSS Lasers?

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
