SPL BZ91-40-7 (912 +/-3NM)

Laser Diodes, Modules

SPL BZ91-40-7 (912 +/-3NM) is a type of laser diode with a range of applications and working principle. What makes it noteworthy is the ability to produce single-frequency light and a wide range of wavelengths, from infrared to red.

The SPD BZ91-40-7 (912 +/-3NM) is a single-mode laser diode package produced by Sumitomo OptoElectronic Products Ltd. It is equipped with a DBR (Distributed Bragg Reflector) laser diode within an optical cavity. This diode works on the principle of Bragg Scattering, in which light emitted by a diode propagates through an optical cavity and is repeatedly reflected between two mirrors that have a particular spacing. This structure makes it possible to generate a single frequency light, contrary to diode lasers that generate multi-frequency light.

The SPD BZ91-40-7 (912 +/-3NM) is distinguished for its specific wavelength range and its narrow spectral width. It is a type of semiconductor laser with a wide range of applications, including eye surgery, medical diagnosis, industrial processing, and material deposition. The diode is able to produce a single wavelength light from the infrared to the red spectrum. This makes it suitable for applications involving high power and wavelength selectivity, such as laser marking and welding. It can also be used in other fields such as machine vision and data transmission, due to its capability to produce a high-contrast uniform light source.

The SPD BZ91-40-7 (912 +/-3NM) has several advantages over other laser diodes. It has a high efficiency with a relatively low power consumption, since its emission wavelength requires less energy than longer wavelengths. Furthermore, it is able to achieve high speed and an excellent output beam quality. Moreover, due to its narrow spectral width and single wavelength emission, it is possible to avoid interference between multiple diodes, which would otherwise diminish the output intensity and reduce the signal-to-noise ratio.

In conclusion, the SPD BZ91-40-7 (912 +/-3NM) is an innovative laser diode package with a successful application in several areas. It is characterized by a wide emission spectrum, narrow spectral width, and a single-mode laser diode. It is suitable for applications that require high power and wavelength selectivity, due to its low power consumption and high efficiency. It also offers advantages such as increased speed, high-contrast uniform light source, and the possibility to avoid interference.
