FAQs

For more questions visit our help center.

How do I choose the right model?

Select based on the wavelength, output power, and fiber connector (e.g., SMA905) you require. Please inform us if you need special modulation.

What are the advantages of your lasers?

Our lasers feature thermoelectric cooling and precise temperature control, ensuring more stable output, superior beam quality, and a longer lifespan for demanding applications.

Can the laser be controlled by an external signal?

Yes. Most models support TTL modulation, allowing you to quickly switch the laser or adjust its intensity via an external signal.

What about product quality and warranty?

We offer an 18-month warranty, and each unit undergoes rigorous aging tests to ensure reliability and a long service life.
