Product Range:
Wavelength Selection:
Absolute wavelength accuracy in a wide spectral range with green, yellow, and red wavelengths.
Green | Yellow | Red |
543nm | 594nm | 633nm |
Output Power Selection:
Output powers may vary based on wavelength and options.
2mW | 5mW | 10mW | 15mW | 18mW | 20mW |
Beam Diameter:
Beam diameters may vary based on wavelength and mode.
0.49mm | 0.63mm | 0.75mm | 0.8mm | 0.88mm | 1mm | 1.5mm |
Polarization:
Randomly Polarized | Random polarization has an electric field vector that fluctuates randomly. |
Linearly Polarized | Linear polarization has an electric field vector that doesn’t change over time or position |
Other Options:
Brewster Window Tubes | Produce a laser beam that is not only monochromatic but polarized as well. |
Fiber Coupling | Can be fiber coupled into a single mode or polarization-maintaining fiber. |
Power Supply | OEM and laboratory power supply options are available. |
Benefits:
- High stability and Low Noise:
- Ensure consistent and accurate results, minimizing the risk of errors and reducing the need for adjustments or recalibrations.
- Long Life and Robust Mechanical Design:
- Minimize downtime and replacement costs, providing peace of mind for customers and reducing the risk of unexpected failures.
- Custom Models:
- Tailor the Helium-Neon modules to your specific needs, ensuring optimal performance for your unique applications.
- Versatile Power Supply Options:
- Use your module in a variety of settings, reducing the risk of compatibility issues and providing flexibility for future changes in power requirements.
- High Coherence Length:
- Coherence length varies from 20 cm (multimode) to more than 100 m, depending on cavity parameters, mirrors, and etalons used.
- Stable Central Wavelength:
- Very stable oscillation frequency of <1 MHz (<0.001 pm @633 nm) with stabilization measures. Non-stabilized lasers can drift in the range of 1 pm.
- High Spectral Purity:
- We can force the laser to oscillate in just one of several emission bands. No spontaneous emission or emission from other bands is detectable.
- Good Beam Quality and Alignment:
- The longer the tube, the easier it is to get a good Gaussian beam profile, good beam quality, and very good angular and spatial alignment with respect to the laser housing.
- Low-Cost:
- Many years of HeNe laser manufacturing have allowed for a more efficient, time-tested process, providing cost-effective, repeatable performance.
