HeNe Laser Systems

Standard HeNe Lasers

Standard HeNe lasers are the most common type, emitting a continuous wave of red light. They are widely used in educational settings, laboratory experiments, and alignment tasks due to their simplicity and reliability. These lasers are characterized by their low power output, typically ranging from 0.5 to 10 mW.

Polarized HeNe Lasers

Polarized HeNe lasers are designed to emit light with a specific polarization state. This feature is crucial in applications requiring precise control over the light's polarization, such as in optical instrumentation and interferometry. These lasers often include internal polarizing optics to maintain the desired polarization state.

Frequency-Stabilized HeNe Lasers

Frequency-stabilized HeNe lasers are engineered to maintain a constant frequency output, essential for applications like metrology and holography. These systems incorporate feedback mechanisms to stabilize the laser's frequency, ensuring high precision and consistency over time.

When selecting a HeNe laser system, consider the following key parameters:

• Wavelength: Ensure the laser's wavelength matches the application's requirements, typically 632.8 nm for red light.
• Output Power: Choose a power level that suits the intended use, balancing between visibility and safety.
• Beam Quality: Evaluate the beam's divergence, mode structure, and coherence length for precision tasks.
• Polarization: Determine if a polarized beam is necessary for your application.
• Stability: Consider frequency-stabilized models for applications requiring high precision.

To assess product quality and reliability, research supplier reputations, review customer feedback, and verify compliance with industry standards. Additionally, consider environmental factors such as temperature and humidity, and ensure the installation site supports the laser's operational requirements, including power supply and mounting options.
