What is a laser and how does it work?


Nanometers for Near-Infrared Spectrum

A laser, short for Light Amplification by Stimulated Emission of Radiation, is an optical device that generates an intense, coherent, and focused beam of light through the process of stimulated emission.


Nanometers for Mid-Infrared Spectrum

. Unlike conventional light sources, lasers emit light in a single wavelength or color with minimal divergence, resulting in a concentrated and highly energetic output.


Nanometers for Visible Spectrum

This remarkable feat is achieved by stimulated emission, a process where photons emitted by excited atoms stimulate other atoms to emit identical photons, creating a cascading effect that leads to a coherent and powerful laser beam.

Specifications For Laser Systems and What They Mean

Power Output

Power output, usually measured in watts (W), indicates the strength of the laser beam. Higher power output generally means a brighter and more intense laser beam, allowing for longer range and increased visibility. However, it’s important to note that higher power lasers may have legal restrictions on their use, so always adhere to local regulations.


The wavelength of a laser system refers to the color of the laser beam and is typically measured in nanometers (nm). Different wavelengths have different properties and applications. For example, red lasers typically have a wavelength of around 630-680 nm, while green lasers are around 520-570 nm. Consider the intended purpose and specific applications when choosing a laser system with the desired wavelength.

Beam Divergence

Beam divergence measures how much the laser beam expands as it travels over a distance. It is usually specified in milliradians (mRad). A lower beam divergence value indicates a more focused and concentrated beam that can reach longer distances with greater precision.

Operating Distance

The operating distance specifies the maximum distance at which the laser beam remains effective. It is influenced by factors such as power output, atmospheric conditions, and target reflectivity. Higher power lasers and those with lower divergence tend to have longer operating distances.

Battery Life

Battery life is a crucial specification to consider, especially for portable laser systems. It indicates the duration for which the laser can operate on a single charge or battery set. Be mindful of the battery life and ensure it aligns with your intended usage requirements.

Safety Class

Laser systems are classified into different safety classes based on their potential hazards. Classes range from Class 1 (no known hazards) to Class 4 (potentially hazardous). Make sure to choose a laser system that aligns with your safety needs and follows applicable regulations.

Why are lasers used?

Lasers find a wide range of applications due to their unique properties. In military and defense contexts, lasers have proven invaluable for:

Precision Targeting and Aiming

Laser systems, such as the INFORMER-RM, provide highly collimated aiming lasers that allow operators to precisely target and engage threats, even in low light conditions. These systems are often used in conjunction with night vision devices, enabling effective operations during nighttime missions.

Anti-Personnel and Anti-Material Capabilities

High-powered lasers have demonstrated their potential as anti-personnel and anti-material weapons. They can be utilized to disable or destroy unmanned aerial systems (UAS), enemy sensors, communication systems, and even engage hostile personnel.

Countermeasure Systems and ISR

  1. Laser systems play a crucial role in defensive operations by serving as countermeasure systems against guided missiles, rockets, and artillery shells. These systems can rapidly engage and neutralize incoming threats, offering an effective layer of protection.
  2. Intelligence, Surveillance, and Reconnaissance (ISR): Lasers find applications in ISR operations, including range finding, target designation, and active imaging. They can assist in gathering critical intelligence and enhancing situational awareness on the battlefield.

    • Wavelength: HEL systems often utilize fiber lasers or solid-state lasers with wavelengths in the infrared spectrum, typically around 1,000 to 1,100 nanometers (nm).
    • Beam Divergence: The beam divergence of HEL systems is usually relatively low, typically less than 1 milliradian (mRad), enabling focused and accurate targeting at longer ranges.
    • Operating Distance: HEL systems can engage targets at significant distances, reaching several kilometers, depending on atmospheric conditions and power output.
  2. Laser Targeting Systems: Laser targeting systems are widely used by the US military to improve precision and accuracy during engagements. These systems facilitate the designation of targets for guided munitions or provide visual cues for ground forces. Common laser targeting systems include:
    • Power Output: Laser targeting systems typically have lower power outputs compared to HEL systems, ranging from a few milliwatts (mW) to a few watts (W), depending on the specific application.
    • Wavelength: These systems employ lasers with various wavelengths, including red (around 630-680 nm) and green (around 520-570 nm), ensuring optimal visibility under different lighting conditions.
    • Beam Divergence: Laser targeting systems often have adjustable beam divergence to accommodate different operational requirements, allowing for precise and adjustable beam widths.
    • Operating Distance: The operating distance of laser targeting systems varies depending on the power output and atmospheric conditions but can generally extend to several kilometers.
  3. Laser Range Finders: Laser range finders are critical tools used by the US military for accurate distance measurement. These devices emit laser pulses and measure the time it takes for the pulse to return, providing precise range information. Laser range finders feature:
    • Power Output: Laser range finders have low power outputs, typically in the range of a few milliwatts (mW) to a few watts (W).
    • Wavelength: They utilize lasers with specific wavelengths optimized for target reflection and detection, commonly in the near-infrared spectrum (around 800-900 nm).
    • Beam Divergence: The beam divergence of laser range finders is typically narrow, ensuring a concentrated and well-defined laser pulse for accurate measurements.
    • Range Measurement: These devices can accurately measure distances ranging from a few meters to several kilometers, depending on the target and environmental conditions.

These are just a few examples of laser technologies employed by the US military. The exact technical specifications of laser systems may vary depending on the specific application, platform, and mission requirements. The US military continues to invest in laser research and development to enhance capabilities across domains such as precision targeting, missile defense, and directed energy systems.
