How can I use the case pin of a 450nm blue laser that has a Zener diode in reverse bias direction and a transconductance amplifier to amplify the changes when small amount of coherent light bouncing of the target makes it back to the lasers silicone junction, changing the wavelength, characteristics, and power output which is regulated by the zener or maybe this is an incorrect approach for a rudamentry interferometer? Please could anyone help with the idea? I was also thinking if pin 1 and pin 3 are solely for LD-ZD in series I could use a bias Tee, pick a part I inside the bandwidth of the diode and add a RF carrier and see if the coherent reflection in light back to junction does the job of interference than measure it. Appreciate any help?
