A laser driver is an electronic device that provides the necessary electrical power and control signals to drive a laser diode. Laser diodes are semiconductor devices that generate coherent light, which is used in a wide range of applications such as telecommunications, laser printing, and laser cutting.
The laser driver provides the laser diode with a stable and precise electrical current to ensure that the laser operates at the desired output power level and wavelength. It also provides protection against overcurrent, over temperature, and other potential hazards that could damage the laser diode.
The laser driver typically consists of a power supply, a control circuit, and a driver stage. The power supply converts the incoming voltage to the appropriate level for the laser diode, while the control circuit generates the control signals that set the laser diode's output power and wavelength. The driver stage amplifies the control signals and drives the laser diode with the appropriate current.
Laser drivers can be used in a wide range of applications, including laser communications, medical devices, scientific instrumentation, and industrial equipment.
Analog Technologies, Inc. has launched various series of laser diode drivers, including analog and digital laser drivers, which can be checked here:
