2. Precise temperature tuning to adapt to complex working scenarios

In precision optics, outdoor equipment, and industrial processing scenarios, environmental temperature fluctuations can easily cause laser wavelength shifts, directly affecting equipment accuracy.

This device has precise temperature tuning at 0.12nm/℃, which can correct wavelength drift through simple temperature control and adapt to complex temperature conditions, greatly improving the environmental adaptability and versatility of 780nm laser output.

3.24h long-term stable testing of industrial grade reliable quality

Long term output stability is the core standard for the industrial implementation of laser devices. We conduct rigorous long-term stability testing on our products:

Under the working condition of 3W frequency doubling light output, continuous 24-hour operation testing was carried out, and the final measured laser output fluctuation range was only ± 1%.

The extremely low power fluctuation confirms the excellent optical consistency and fatigue resistance of the device, which can adapt to long-term experiments, uninterrupted industrial operation and maintenance scenarios, and ensure the continuous and stable output of 780nm laser.

4. Widely adapt to multiple fields to empower high-end optoelectronic innovation

With four core advantages of 5W high power, 50% high conversion efficiency, precise temperature control tuning, and 24-hour ultra-low fluctuation, this 780nm frequency doubling waveguide is widely used in quantum communication, precision measurement, spectral analysis, scientific research experiments, high-end laser equipment integration and other scenarios. It is the preferred core device for visible light frequency conversion systems.

Compared to traditional devices, our thin-film lithium niobate PPLN waveguide structure is more compact, has higher coupling efficiency, and lower long-term losses, balancing high performance and high integration, and is suitable for upgrading various high-end optoelectronic devices.

Deeply cultivating the field of thin film lithium niobate optical devices, we focus on the core pain points of the industry.
