Estebans system was different and quite clever.
He modulated the laser output so the reflected wave is close to the modulated frequency, so you detect the reflected wave not the laser frequence.

Agree, Estebans system is working, but his system cannot detect nothing like gold or silver.
He pull the idea from laser spy microphone where voices modulate laser beam:

Nice to play with such creation, but conceptually wrong and unusable in detecting things of value.
