Pulsed Energy Mode :
Pulsing the Sapphire Portable Diode Laser energy will allow some cooling of the tissue between emissions of
energy. The “duty cycle” is the percentage of the time that the system is emitting energy. The pulses per second,
the duty cycle and the energy intensity per pulse determine the average power.
In the pulsed mode, the Sapphire Portable Diode Laser is programmed to deliver 10 pulses per second with a
duty cycle of 50%. It produces 1 energy pulse with 1 period of rest with no energy between each pulse. The
result is an average power per second that will be 50% of the laser’s setting. Therefore, when using pulsed
energy, you will have to adjust your power upward in order to achieve the same rate of work at the same power
set in CW.
Tissue Responses to Laser Energy:
Maximum results will be achieved by regulating the power and the speed that the operator moves the Fiber Optic
Tip. Tissue charring is an undesirable after-effect of too much power, or of the Tip moving too slowly. Always use
the least amount of power that is required to complete your procedure. The ideal tissue response will show little
or no discoloration after treatment and will result in less residual damage and faster healing. Avoid penetrating
or damaging the periosteum, and do not attempt to use the laser on alveolar bone. Because the 808 nm laser
energy is attracted to melanin and hemoglobin, power must be reduced when treating patients with darker soft
tissue. Always begin with the lowest power you can use to remove or modify target tissue.
Installing and Replacing Single-Use Fiber Optic Tips
The Fiber Optic Tips conduct laser energy from the laser diodes to the tissues. These fi bers are made of silica
with a polymer cladding.
Note that there are potential hazards when inserting, steeply bending, or improperly securing the fi ber Optics
to the handpiece. Failure to follow these recommendations may lead to damage to the Fiber or delivery system
and/or harm to the patient, staff, or laser operator. If the aiming beam spot is not present at the distal end of
the delivery system, its intensity is reduced, or it looks diffused, this is a possible indication of a damaged or
malfunctioning delivery system. If the issue is not resolved by use of another Fiber Optic Tip, return the system
to the manufacturer for repair.
