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 signal. Here’s the RF transformer I was looking at. RF Transformer Is this possible?
Would a solar cell connected to an an oscilloscope work as a receiver at such high frequencies see pic? (I would replace the stereo with an oscilloscope)
