Narrow Linewidth Laser - Global Industry Market Analysis Report 2020-2031

Narrow linewidth lasers are optical devices that emit laser beams with an extremely small optical linewidth, which means they have a very narrow optical spectrum. The linewidth of a laser refers to the width of its spectral line, typically measured as the full - width at half - maximum (FWHM) of the power spectral density of the emitted light. For narrow linewidth lasers, this value is usually in the range of several kilohertz (kHz) to a few megahertz (MHz), much narrower than that of conventional lasers.

These lasers are generally associated with single - frequency operation. They oscillate on a single resonator mode, featuring low phase noise and thus high spectral purity. In addition, they often exhibit low intensity noise. To achieve a narrow linewidth, several key factors need to be considered in the laser design. Firstly, single - frequency operation must be ensured. This is more achievable when using a gain medium with a small gain bandwidth and a laser resonator with a short length (resulting in a large free spectral range). The aim is to maintain long - term stable single - frequency operation without mode hopping. Secondly, external noise influences should be minimized. This requires a stable resonator setup, preferably a monolithic one, along with measures to protect against mechanical vibrations. For electrically pumped lasers, a low - noise voltage or current source is necessary, and for optically pumped lasers, a pump source with low intensity noise is required. Also, any optical feedback should be avoided, for example, by using a Faraday isolator. Thirdly, the laser design should be optimized to minimize laser noise, especially phase noise. A high intracavity optical power and a long resonator can be beneficial, although achieving stable single - frequency operation is more challenging with a longer resonator.

There are several types of narrow linewidth lasers. Among semiconductor lasers, distributed feedback laser diodes (DFB lasers) and distributed Bragg reflector lasers (DBR lasers) are common. DFB lasers use a grating structure within the laser cavity to generate a narrow linewidth output, typically operating in the 1.5 - or 1.0 - μm wavelength region, with an output power of tens of milliwatts (or possibly above 100 mW) and a linewidth of several megahertz. DBR lasers also contribute to narrow linewidth output. Significantly smaller linewidths from semiconductor lasers can be obtained by extending the resonator with a single - mode fiber containing a narrow - bandwidth fiber Bragg grating or by using other types of external - cavity diode lasers, where ultra - narrow linewidths of a few kilohertz or even below 1 kHz can be achieved. Small fiber lasers in the form of distributed feedback lasers (with the resonator formed mainly by a special fiber Bragg grating) can generate tens of milliwatts of output power with a linewidth in the region of a few kilohertz. Higher output powers can be achieved with longer distributed Bragg reflector fiber lasers or unidirectional fiber ring lasers, sometimes in combination with a fiber amplifier. Diode - pumped solid - state bulk lasers, such as nonplanar ring oscillators, can also have linewidths of a few kilohertz, along with relatively high output powers on the order of 1 W, and they can operate at wavelengths like 1064 nm, as well as other wavelengths in the 1.3 - or 1.5 - μm regions.

The market for narrow linewidth lasers has been growing steadily in recent years. The increasing demand for high - precision optical applications across various industries is a major driving force. In the field of optical communications, especially for long - haul and high - speed fiber - optic transmission systems, narrow linewidth lasers are crucial. Their narrow linewidth helps to reduce chromatic dispersion and improve the quality of optical signals over long distances, enabling higher - capacity data transmission. In the area of sensing, narrow linewidth lasers are widely used in fiber - optic sensors for applications such as strain, temperature, and pressure sensing. Their high coherence and stable frequency characteristics allow for highly accurate and sensitive measurements. For example, in the oil and gas industry, they are used in downhole sensing applications to monitor reservoir conditions. In the scientific research community, narrow linewidth lasers are essential tools for high - resolution spectroscopy, which is used to study the structure and properties of atoms and molecules. They are also used in atomic clocks, which are crucial for applications such as global positioning systems (GPS) and high - precision timekeeping. The development of emerging technologies such as quantum computing and quantum communication also creates new opportunities for narrow linewidth lasers. These applications require lasers with extremely stable frequencies and narrow linewidths to ensure the accurate manipulation and transmission of quantum states. However, the market also faces challenges. The complex manufacturing process and high - end technology requirements result in relatively high production costs, which may limit their widespread adoption in some price - sensitive applications. Additionally, the continuous need for improving laser performance, such as further reducing the linewidth and increasing the output power while maintaining high stability, poses technical challenges for manufacturers. There is also intense competition among laser manufacturers, both in terms of technology innovation and cost - effectiveness.
