Product Description:
The LN series of narrow linewidth lasers is renowned for its
exceptional characteristics, including high spectral purity, a long
coherence length, and minimal phase noise. These lasers are
meticulously engineered to deliver a stable and precise light
output, making them indispensable for a wide range of sophisticated
applications.
In the realm of gravitational wave detection, these lasers play a
crucial role by providing a stable and coherent light source that
is essential for the sensitive instruments used to detect the
minute distortions in spacetime caused by passing gravitational
waves. Their high spectral purity ensures that the measurements are
free from unwanted noise, thereby enhancing the accuracy of the
detection process.
For cold atom physics, the LN series lasers offer an ideal light
source for manipulating and studying atoms at extremely low
temperatures. The long coherence length and low phase noise of
these lasers enable researchers to maintain precise control over
the atomic states, facilitating groundbreaking experiments in
quantum mechanics and precision measurements.
Coherent optical communications also benefit greatly from the use
of these narrow linewidth lasers. The high spectral purity ensures
that the optical signals remain clear and distinct over long
distances, reducing the error rate and increasing the overall
efficiency of data transmission. This is particularly important in
modern telecommunications, where the demand for high-speed and
reliable data transfer is ever-growing.
Optical precision measurements, such as those required in metrology
and materials science, rely heavily on the consistent and accurate
output of narrow linewidth lasers. The minimal phase noise and long
coherence length of the LN series allow for extremely precise
measurements of physical quantities, enabling advancements in
fields such as nanotechnology and semiconductor manufacturing.
Lastly, in the field of microwave photonic signal processing, these
lasers are instrumental in generating stable microwave.

Advantages of Narrow Linewidth Light Sources:
●The measurement accuracy of high-speed ultra-precision laser
interferometers is limited by the wavelength stability of the
probing laser and the coherence coefficient of the interferometer.
●High-Power Output: 1064nm narrow linewidth light sources provide high-power output,
enhancing the coherence coefficient of the interferometer.
●High Wavelength Stability: This improves measurement accuracy significantly.
By utilizing ultra-narrow linewidth solid-state lasers, the
measurement accuracy of laser rangefinders can be elevated to
achieve measurement precision below the atomic scale within a range
of 300mm.
