Pulse energy is adjustable in power increments from 5 to 100W. Pulse rate is usually 60 Hz. The com-
bination of pulse energy and pulse rate define an operating point.
A total energy display with a clear function allows the user to keep track of the total energy used from the last
time the display was cleared.
A delivery system fiber is attached to a fiber port on the front of the system console. The delivery fiber comes
in a number of styles to meet the requirements of various applications (angled, etc.). The system will not fire
without a delivery fiber attached.
Once the system operating parameters are selected, the user selects the READY mode, positions the fiber
output at the treatment site, then depresses the footswitch to deliver treatment pulses at the rate and energy
selected. The treatment delivery will continue until the footswitch is released. The shutter opens and
treatment delivery begins without delay.
Fault monitoring continues for as long as the system is turned on, and any detected fault is reported on the
LCD color display.
An emergency off button is located on the console next to the key switch. Depressing it will turn the system
off. The system may also be turned off by moving the key to the off position or by turning the main breaker
off.

4.1.2 Functional Overview
The VersaPulse Powersuite can hold up to four YAG rods. The maximum average power and wavelength(s)
the system provides is determined by the number and type of rods used.
Refer to the VersaPulse Powersuite Block Diagram in Section 8 page 8-3. The VersaPulse PowerSuite has
four identical YAG cavities arranged in a 2x2 matrix. Each cavity includes its own rod, flash lamp, high
reflector, output coupler and a set of two relay mirrors. The rods are operated sequentially - never together -
thus each rod is capable of producing the maximum selectable pulse energy. Each rod delivers every fourth
pulse. This sequential firing allows the VersaPulse Powersuite to provide four times the pulse rate as could be
provided by a single rod, increasing the maximum average power available by the same factor (four).
For example, at the 40 Hz pulse rate, each rod is operating at 10 Hz, and is producing 1/4th of the average
power. As a result, the VersaPulse PowerSuite laser provides higher selectable pulse rates and higher average
