Frequently Asked Questions

Facet coating is a technique used to reduce the reflectivity of the laser cavity's end facets, which can cause optical feedback and degrade the laser's performance. By applying a thin layer of anti-reflective coating to the facets, the reflectivity can be minimized, resulting in higher output powers, better beam quality, and improved reliability.

Temperature and current are critical parameters that can affect the performance and lifetime of CW semiconductor lasers. High operating temperatures can cause degradation and failure of the laser due to increased thermal stress, while high currents can lead to increased heating, decreased efficiency, and premature aging. Careful control of temperature and current is essential for optimizing the performance and reliability of CW semiconductor lasers.

Yes, CW diode lasers are commonly used in medical and scientific applications, including biomedical imaging, microscopy, and spectroscopy. Their high efficiency, compact size, and ease of integration make them well-suited for these applications, where precise and reliable performance is critical.

Wavelength stabilization is a technique used to stabilize the output wavelength of CW semiconductor lasers by using a feedback mechanism to compensate for changes in temperature or current. This results in a more stable and consistent output wavelength, which is critical for applications such as optical communications and spectroscopy.

Quantum well design is a technique used to improve the efficiency and output power of CW semiconductor lasers by using a series of ultra-thin semiconductor layers to confine the electrons and holes in the laser's active region. This results in a higher gain, lower threshold current, and reduced heating, which can improve the laser's performance and lifetime.

Distributed feedback (DFB) lasers are a type of CW semiconductor laser that use a grating structure to provide feedback for the laser cavity. This results in a single-mode output with high spectral purity and narrow linewidth. DFB lasers are widely used in optical communications and sensing applications, where stable and precise performance is critical.

External modulation is a technique used to improve the performance of CW diode lasers by modulating the input signal externally, rather than directly modulating the laser itself. This can improve the laser's bandwidth, reduce noise, and enable higher data rates in optical communications and data networking applications.

Gain-switched lasers are a type of CW semiconductor laser that use a pulsed current to achieve a high peak power output. They offer several advantages over other types of CW semiconductor lasers, including higher peak powers, faster rise times, and lower costs. Gain-switched lasers are used in a variety of applications, including range finding, LIDAR, and materials processing.

The first useful semiconductor laser was made by R.N. Hall in 1962 which was composed of GaAs materials that emitted in near infrared at 0.8 µm. The semiconductor laser is similar to transistor, has the appearance of a LED but the output beam has the characteristics of a laser. The application that was the main driving force in the development of semiconductor lasers was in the field of long distance communications but at this moment the use of this laser in compact disc players constitutes their largest single market. Using semiconductor laser gives an advantage of low power consumption requirements.
