About the Lasers
In 2004, the external appearance of the Apogee 5500/Acclaim 7000 laser system was changed to
include a sleeker look and the fiber exiting the upper chassis on an angle to the back. Included in
the new laser system is the Apogee Elite, which has both of these resonators, combined and
coupled to the same output fiber. All the lasers are built on nearly identical platforms with the
only major difference being the optical rail assembly. High voltage systems, fluid systems and
control electronics are the same. For this reason, only one manual is required to repair and
maintain all three lasers. NOTE: If the laser has a white enclosure with purple trim, it is the older
design and requires the Apogee 5500/Acclaim 7000 Service Manual, document #850-1247-000.
The laser display is available in various languages and is configured prior to shipping. If for any
reason the language needs to change, first connect a laptop computer, described in “Appendix A”
on page 67. Then start the laser in the testall mode, as described in the Final Test and
Calibration Procedure. At the laptop TESTALL menu, choose selection “m” to cycle through
the available languages. When the desired language is displayed on the screen, cycle the power
and the laser will run with the display in that language.

Section 2 EQUIPMENT SAFETY
Introduction
As with any electrical equipment, there are potential hazards involved with the operation and
servicing of the Apogee Elite/Apogee 5500/Acclaim 7000 laser systems. This section of the
technical guide identifies these potential hazards and suggests precautions to avoid them.
Potential Hazards
Optical Hazard
The Apogee 5500 laser generates laser light at a wavelength of 755 nm with a maximum energy
of approximately 45 joules delivered from the handpiece. The Acclaim 7000 laser generates laser
light at a wavelength of 1064 nm with a maximum energy of approximately 63 joules delivered
from the handpiece. The Apogee Elite laser generates laser light at a wavelength of 755 nm and
1064nm with a maximum energy of approximately 45 joules at 755nm and 63 joules at 1064nm
delivered from the handpiece.
Greater energies can be generated from the laser head especially during service operations. At
these wavelengths and energy levels, serious and permanent damage to the eyes can occur when
there is direct or even indirect optical exposure.
WARNING: These lasers produce laser light each time the flashlamps fire. Do not look
directly at laser resonator as the flashlamps fire or severe and permanent eye damage may
occur. Make certain to wear the correct laser eyewear for the wavelength you are testing.
Please adhere to the following precautions to avoid optical damage during the operation or
servicing of the laser:
♦Ensure that everyone present during service procedures wears the appropriate protective
eyewear recommended by Cynosure.
♦Never look directly into the laser light, even while wearing protective eyewear.
♦Mark treatment rooms clearly to avoid unexpected entry during treatment or servicing.
♦Limit entry to the treatment or servicing room to trained, necessary personnel only.
♦Cover windows and other openings in the treatment room to avoid the inadvertent escape
of laser light.
♦Cover reflective objects, such as jewelry or mirrors, which could reflect the laser beam to
an area other than the intended treatment area.
♦Put the laser into the standby mode when the laser is not in use.
♦Ensure that everyone present during service procedures can shut down the laser in an
emergency.

Page 10 of 70 850-1257-000, Rev. 2 Cynosure, Inc.
Electrical Hazard
The system requires 220 VAC ± 10%, 30 A, 50-60 Hz, single-phase electrical service to operate.
WARNING: Even when the laser is off and the AC line cord is disconnected, DC
voltages on various laser components, such as capacitors may exist. This can present a
potentially fatal electrical hazard during service procedures. Proceed with caution!
Take the following precautions to avoid an electrical shock during servicing:
♦Always turn the laser off and disconnect the AC line cord from the receptacle before
removing the protective housing of the laser system.
♦With the laser off, allow the dump resistors to dissipate the energy in the Pulse Forming
Network capacitors to a safe level, approximately 45 seconds. Monitor the voltage on the
capacitors with a DVM probe to ensure it is at a safe level.
♦If it is necessary to test or adjust any electrical component while the system power is on,
be careful not to touch any electrical components with bare fingers. Use only appropriate
probes or insulated tools.
♦Become familiar with the electrical schematics and layout of the system before
attempting to service the laser.
If the AC must be connected during service routines, exercise caution around mains connected
components, such as power supply feeds, circuit breakers, key switches, etc. A remote interlock
fault condition will reduce high voltage electrical hazards to service personal. This fault
condition disables the high voltage power supply control and simmer circuits, as well as ensuring
that the dump relay is closed, grounding the potential of the pulse forming network. When
possible, remove the remote interlock plug during “live” service routines.
Grounding
Even when the laser is turned off and the AC line cord disconnected, high DC voltage levels may
remain. Before performing any procedure, use a shorting stick to ground all interior components.
The main capacitor bank stores large amounts of electrical energy. Measure the voltage on the
capacitor bank before attempting any service. Ground the capacitor bank with a shorting stick for
at least five seconds.
WARNING: Do not attempt to short directly (i.e., with a screwdriver) or a potentially fatal
electrical shock can occur.

Technical Guide
Fire Hazard
When the laser beam contacts any exterior surfaces, the surface absorbs the laser energy, which
raises the surface temperature of any flammable substance. Service personal must take the
following precautions.
♦Always keep a small fire extinguisher and water in the treatment room.
♦Never direct the laser beam onto any surface except a power meter or an appropriate
beam dump.
Hot Water Hazard
The laser system uses a hot water system to maintain the laser medium at 65 °C. This water is
very hot and could cause scalding. Do not perform any maintenance on the water system while
hot. Always let the system cool down before changing the deionizing filter or adding deionized
or distilled water.
Service Equipment
A full complement of tools is required to service this laser system. It is expected that service
personnel carry at least the following tools to an installation or laser repair call.
Hand Tools
♦Screwdriver set
♦Allen Wrench or Hex Head Ball Driver set
♦Nut Driver set
♦Adjustable wrenches
♦Wire cutters
♦Wire strippers
♦Needle nose pliers
♦X-ACTO knife

Section 3 LASER DESCRIPTION
Main Components
This section of the manual gives a detailed description of the main components of the laser
systems. All lasers share common elements, as outlined below.
♦An active medium in which laser action takes place—the laser rod (or rods in the case of
the Apogee Elite laser system),
♦A source of pump energy—the inert gas-filled flashlamps,
♦An optical resonator—the front partial reflector and rear 100% reflector,
♦A control system—the system control electronics,
♦A power supply that provides electrical power to the flashlamps.
Figure 2A illustrates the system diagram of the Apogee Elite laser with its two laser resonators.

Figure 2C–Main Components
High Voltage Power Supply
The High Voltage Power Supply (HVPS) is a modular inverter capacitor charging power supply.
This device accomplishes the primary energy conversion for the laser. It converts input power of
220 VAC, 50 or 60 Hz, to a controlled, high-voltage direct current. A software controlled low-
voltage analog signal is used to set the appropriate HVPS output voltage level during laser
operation. When enabled, the power supply charges the capacitor bank through the capacitor
bank fuses. The laser control board also inhibits, enables and regulates high voltage output level
depending on the state of the laser.
The maximum voltage is 900 V and the charge rate is approximately 3700 joules/second. For
demonstration purposes, the system can be run on 120 VAC 15A Service. To make this change,
please contact Cynosure Service.

Page 16 of 70 850-1257-000, Rev. 2 Cynosure, Inc.
Fuse Board
WARNING: High Voltage Danger! In the event of fuse failure, the capacitor bank may
retain dangerous energy levels at high voltages. Please approach and handle with extreme
caution.
The fuse board contains six 25-amp, 600-volt, Slo-Blow type fuses. Four of these fuses are
connected to a pair of high voltage storage capacitors. The fuse board is designed to protect the
storage capacitors against any excessive current draw that may occur with a short, such as a
flashlamp or another capacitor shorting to ground.
Capacitor Bank
WARNING: High Voltage Danger! The capacitor bank stores dangerous voltage and
energy levels during laser operation. Please handle with extreme caution.
The capacitor bank, see Figure 3, consists of eight 10,000 µF, 450-volt capacitors coupled
together in a series/parallel configuration to provide a 900-volt, 8-kilojoule energy source. This
large amount of stored energy must be regarded carefully.
Only a fraction of this stored energy is drained off for a given laser pulse. In a fault condition,
the stored energy is discharged through the dump resistors to ground.
