since these also determine focal power. Consequently, the amplifier drive current
must be kept within a close tolerance of the design point.
In applications that require the laser output power be lowered to reduce gain
without sacrificing beam characteristics and focal power, the Patara laser achieves
a corresponding reduction of power by increasing the loss of the optical cavity
while maintaining the gain at a constant level. This added functionality of
accepting and executing power level commands is built into the accompanying
eDrive electronic system.
The Patara laser consists of three interconnected subsystems. The optics
subsystem contains the laser oscillator, the eDrive electronic subsystem provides
power and control for the laser transmitter, and the chiller provides thermal
control. The user must supply prime power and cooling to the optics subsystem.
The interface relationships among these subsystems are illustrated in Figure 1-1.

NOTE:
Figure 1-1 shows an external TEC Controller, which is not standard. Typically
the TEC Controller is located inside the eDrive (for -0150 and later configurations).
