[For designers] Watch anytime! ROHM's "semiconductor laser" explanatory videos

A semiconductor laser is an optical device called a laser diode or LD.
Laser light has monochromaticity, straightness, coherence, focusing, and pulse response characteristics, and is used in optical disks (OPU), laser printers, multifunction machines, and a variety of other applications.
A semiconductor laser that scans spatial information by emitting a laser beam and performs 3D sensing to determine the presence or absence of objects and their distance.
In recent years, lasers have been used as light sources for triangulation, TOF (Time of flight), LiDAR, etc., and are also used for sensing purposes. They are being used in the mobility field as well as in everyday electronic devices and
There are high expectations for this technology as it will meet social needs for safety and security, as well as automation and labor savings in a wide range of fields, from security measures to industrial machinery.
ROHM's semiconductor lasers boast industry-leading production volumes,We have a lineup to meet a wide range of needs.
This page features a video introducing situations in which semiconductor lasers are used and the benefits of using ROHM products.

<1> Semiconductors/LiDAR Opening Up Industrial Equipment [Grossberg x ROHM Interview Video]

"What is a semiconductor laser?" "How will it be used in the industrial equipment market?" "What characteristics are, How will it contribute to the industrial equipment market?" etc.
A detailed discussion was held. Please watch it. (This is a video of a conversation between ROHM and Satoshi Oyama of Grossberg LLC, a company that provides consulting and research for the semiconductor industry.)

<2> What are the advantages of “high-power semiconductor lasers” and “VCSELs”?

ROHM's strengths in "metal can type high power semiconductor lasers" and "surface mount type VCSELs"
High-power semiconductor lasers are used in robot vacuum cleaners, AGV (Automated guided vehicles)・ They are installed in service robots, etc. VCSELs are being considered for face recognition, industrial robots, driver monitoring, etc.

<3> Features and lineup of high-power semiconductor lasers

The industry's narrowest "emission width of 35 μm" allows high light density and long distance measurement! This product has the advantage of being less susceptible to sunlight noise as it has little wavelength change due to temperature change.

<4> Semiconductor laser lineup for sensors and application introduction

ROHM has a lineup of products that can be used for a variety of applications. In recent years, our products have been adopted and considered for use in obstacle detection, intrusion detection, nighttime infrared lighting, distance measurement, and particle detection.
