AnonymousGuestAwesome inprovement.
I know you just changed that patients life for the better.
Congrats!
etienneSpectatorThanks Ron!
And also thank you for sharing your case on the forum!! Without guys like you and the other regulars on LDF we would all be in the dark.
Take care
Etienne
Robert Gregg DDSSpectatorEtienne,
Ditto on that awesome by Ron. Ditto the kudos to Ron for the post.
However you deliver the total joules, it doesn’t matter all that much as long at the basic parameters are short pulse 20 hz, the power is relative to comfort and spot size over the area.
Great service!
Bob
etienneSpectatorThanks Bob!
If the short pulse is that important, can it be done with a diode?
I know of people who have tried and failed with diodes. Do you know of successful cases?
Take care

Robert Gregg DDSSpectatorHi Etienne,
Diodes are continuous wave, and have no ability to attain the peak powers that a FRP Nd:YAG can with the short pulse duration (intensity of beam). The best they can do is interrupted gated pulse with no true peak pulse power–just a garden hose effect of photons vs a crimped and released hose.
Therefore CW diodes are more like the long pulse durations and we know that mostly warms the tissues. Good for hemostasis when applied properly, just not so good for consistent results in biostim.
That and 20 hz seems to be extremely critical.
Good discussion!
Bob
etienneSpectatorWhy can a diode not achieve the high peak energy that a FRP Nd:YAG can? Due to the way that the laser energy is actually created?
I recall that conventional laser is brought about by electron stimulation, emission and radiation (based on Einstein’s postulation) whereas diode laser light is brought about by electrical charging of a diode?
Somebody told me once that it would be possible to achieve the same energy levels with a diode but that the power supply would be the size of my operatory and such would not be economically viable.
Any thoughts?
Take care
