Spectra-Physics InSight X3 - Power Supply Controls and Connections

IPS-300 Power Supply
Controls, Indicators, and Connections 3-4
Figure 3-3 Mating emission connector
Sync Out connector (SMA)—Typically connected to a frequency counter or to a 50 Ω
oscilloscope input for monitoring the laser head photodiode signal. Runs at the
80
+/-0.5 MHz repetition rate of the laser. A typical waveform is shown in Figure 3-4.
The signal amplitude shown is approximate 600 mV peak-to-peak.

IPS-300 Power Supply
The IPS-300 power supply is air-cooled. It provides high-current DC power to the laser
diode in the InSight
X3 laser head and low-current DC power to the laser head control
circuits. It also provides clean, dry air to the laser head to keep the laser cavity free of
contaminants.
This section defines the user controls, indicators and connections of this power supply.
The front and rear panels are described from left to right, top to bottom.
