What is a Laser Diode Driver

Generally speaking, the laser diode drivers are precisely constant current sources that are known for them being linear, noiseless and accurate as well and as such will be used to deliver just the required amount of current to the laser diode that it requires to perform a specific application. As a user you choose whether to keep the laser diode or photodiode current at a constant or to use at wheel level. The control system will then drive the current to the laser diode safely and in the required levels.

By and large, the laser diode drivers happen to vary greatly in their set features and performance as well. Read on and see some of the things and basics worth knowing of when it comes to laser diode drivers.

We will first take a look at some of the facts and basics on laser diodes. By and large, the laser diode drivers happen to serve the main purpose of supplying current to the laser diodes. There are a number of uses that exist for the laser diode. Talking of some of the most common applications that you will find the laser diodes put to include those such as remote sensing, medical diagnostic and analytical equipment, welding and material processing, particle sizing and counting and in spectroscopy in a whole list of other applications out there. This is often indicated in most application settings by the initials or short form, LD.

The other basic aspects to know of when talking of the laser diodes and drivers are the photodiodes that we already have had a mention of above. There are some instances where a monitor photodiode may come as an integrated feature in the laser diode package. Oftentimes, you will come to notice the fact that the monitor photodiode that so comes as an integrated component with the laser diode drivers will in most cases be producing a current that is equal or thereabouts to the output laser diode optical power. Mark the fact that in most cases the laser diode packages will differ widely one from the other and as well in most cases the photodiode transfer will as well get to vary equally as well. As for their indications, they are as well abbreviated, PD and will be indicated as well with the wavy arrows on the device.

One other feature and aspect of the laser drivers that needs to be known is the Feedback Mode. In this regard, it should be noted that your laser diode drivers will in most cases allow control based on either laser diode current or photodiode current. In case the laser diode current is used as feedback, then the control system as we had already hinted above will try to keep it constant. It is always the case at such times that the output of the Adjustable Current Source will not vary in the case where there is used the laser diode current as feedback.
