The automotive
industry has been registering significant growth over the past few years, which
can majorly be attributed to the rise in people’s disposable income and strong
economic growth in developing countries across the globe. In addition to this,
the automotive industry is actively engaged in the development of autonomous
and connected cars for providing consumers with enhanced driving experience.

Moreover, the demand for luxury cars has also been on the rise because of the
improving living standards of people in several countries. These vehicles make
wide usage of laser diodes, which is why their demand is increasing as well.
Laser diodes are
semiconductor devices which generate coherent, high-intensity light. These
devices are quite similar to light emitting diodes (LED); however, unlike LEDs,
their PN junction generate coherent radiation, which means that the light waves
produced have the same phase and frequency.
Apart from this, the
demand for OPSL is also expected to increase considerably in the years to come,
due to its advantages, including its unique wavelength flexibility that allows
scaling and its ability to match with wavelength needs of several applications.
In terms of operational mode, pulsed and continuous-wave are two types of laser
diodes.
Owing to the wide application areas of these devices, the global laser diode market is projected to grow at considerable pace in the near future. The two types of laser diodes are optically pumped semiconductor laser (OPSL) and injection laser diode (ILD). Between these two, the demand for ILD was higher in the past.
In the coming years, the demand for pulsed laser diodes is predicted to
increase, owing to their high peak power and excellent power stability with
temperature. Some other advantageous optical characteristics of pulsed laser
diodes are the ruggedness of diodes and their small and compact size.
