Laser Diode use in the Industry

laser diode for industry

A diode is a device that conducts current in one direction and limits the current in opposite direction. A laser diode given as the name suggests works in the same principle. A laser diode drivers supply current and voltage from a single laser diode to multiple laser diodes. The drive also protect the laser from oversupply of current.

Rising demand of LIDAR for vehicles, 5G telecommunication, medical devices, diagnostics and surgical treatments and others will increase interest in laser diodes and subsequently interest in laser diode drivers will increase. Laser headlights in cars can travel twice as much distance in comparison with standard LED headlights. BMW and Audi has launched cars with laser full beam. Rising demand of automotive laser headlamps is anticipated to increase interest in laser diodes and subsequently increase demand for laser diode drivers.

Rising transition to 5G mobile technology from 4G mobile technology and broadband internet are anticipated to boost need for laser diodes and subsequently increase interest in laser diode drivers.

Rising demand of semiconductor photolithography, mask-less lithography and 3D printing can also be anticipated to increase demand for laser diodes and subsequently laser diode drivers. Rising demand of non-lethal weapons including PHaSR (Personal Halting and Stimulations Response Rifle) designed to use laser beams to temporarily blind enemy will increase interest in laser diodes and subsequently need for laser diode drivers. Green laser devices is expected to produce window of opportunity for laser diode industry and subsequently for laser diode drivers. Among the major restrains of laser diode is its degradation with time. So with duration of time, laser diodes consume more current to make same optical output. In the event of current flow beyond a spot the optical output falls abruptly and diode is damaged irreversible which is referred to as catastrophic optical damage (COD). This really is expected to decrease need for laser diode and subsequently laser diode drivers.

The laser diode driver market when segmented by product are seed laser diode driver, pulsed laser diode drivers, CW (continuous wave) laser diode driver as well as others.

By end use industries, the marketplace is segmented into industrial, communication & optical storage, military, healthcare, instrumentation & sensor and others. Nearly all laser diode drivers are Pulsed laser diode drivers and CW laser diode drivers. Among end use industries automotive and healthcare are required to increase need for laser diode and subsequently demand for laser diode drivers will increase.

The marketplace when segmented by geography are North America, Europe, Asia Pacific (APAC), Middle East & Africa (MEA) and South America. APAC with major automotive, telecommunication and manufacturing hub is anticipated to be the fastest growing marketplace for laser diode and subsequently demand for laser diode drivers will increase. North America and Europe are among the largest market for laser diode drivers due to presence of major automotive industry in those regions.

A number of the major firms in laser diode driver market are Linear Technology (the U.S), Analog Devices (the U.S.), Maxim Integrated (the U.S), Newport Corporation (the U.S), Texas Instruments (the U.S), Wavelength Electronics (the U.S), Intersil (the U.S), Monocrom (the U.S), Microchip (the U.S), IC-Haus (Germany) amongst others.
