analog modulation is easily possible. If the task requires the laser output to be amplitude-modulated at audio frequencies or higher, it can still be easily done by directly modulating the current source. If a digital style of pulse is required where the leading and trailing edges are sharp and discontinuous, modulation of the
Laser-sound: optoacoustic transduction from digital …
https://www.nature.com/articles/s41598-020-78990-z
The pulsed nature of the laser-generated acoustic waves indicates the need for a digital audio modulation to transcode complex sound signals, in analogy to the well-established pulse streams used ...

https://electronics.stackexchange.com/questions/399600/amplitude-modulating-a-simple-laser-using-an-rf-transformer
I know I can modulate a laser using an audio transformer see pic and website below. Pen Laser website. I was wondering if it’s possible to modulate a simple pen laser using RF signals in the RF range of 1Mhz-100Mhz range? I was thinking of replacing the audio transformer with a RF transformer and using a function generator to generate the RF ...
Transmission of Stereo Audio Signals with Lasers
https://scholarworks.uark.edu/cgi/viewcontent.cgi?article=1030&context=eleguht
With the original analog audio signal in a digital form, it may be transmitted with a laser. This process requires a fast-switching BJT or MOSFET driver that is capable of switching at the frequency of the carrier signal. The laser driver and laser beam pulse for different lengths of time as shown in the bottom plot of Figure 2.

The electronic modulation circuit controls the power delivered to the laser diode, so it is directly turning the laser on and off. This type of modulation can also control the output power of the laser by reducing the electrical power delivered to the laser diode. The maximum response frequency of this type of modulation is usually around 30 ...

In principle, laser communication systems resemble the modems that we have used in our homes since the rise of the Internet. Modem stands for MODulation-DEModulation, a process in which digital information is converted to analog for transmission, then back again. Early acoustic modems used sound waves for transmission over phone lines.
