1.4.3 Laser Emission Levels
The Series 101 lasers run continuous wave (CW) at 1064 nm or 1319 nm. Power will not
exceed 425 mW.
Laser diode emission is contained within the laser head. A filter glass on the aperture window
reduces escaping diode light to less than 1 µW. The diode emission wavelength is 800 ±15 nm.
Reproductions of the labels on the Series 101 are given in Figure 1-12.
1.4.4 Safety Features
Lightwave's Series 101 incorporates several safety features to minimize chances of damage as
a result of exposure to laser emission. Locations of the safety features and labels on the laser head
are given in Figure 1-13. (Controller safety feature locations are shown in Figure 2-1.)
Aperture Shutter
The aperture shutter is located on the front of the laser head and manually operated. To open
the aperture and allow radiation to exit through the aperture, the shutter should be slid out. With the
shutter closed an orange dot will be visible across the aperture, and laser emission will be blocked.
Key Switch
Turning the Key Switch (located on the controller front panel) to the ON position supplies
electricity to the laser head and control electronics. The laser cannot emit radiation unless the key is
turned to the ON position. The key cannot be removed if the switch is turned to the ON position.
Simply turning the Key Switch to the ON position does not necessarily imply the laser is emitting
radiation, since the laser may be in the Standby Mode or the aperture shutter may be closed.
Safety Interlock
The safety interlock is located on the rear of the laser head and allows the user to externally
disable the laser for safety purposes. An example would be configuring the laser such that the
interlock opens/closes when a door is opened/closed. The safety interlock is shipped with an
"enable" jumper plug installed.
To utilize the interlock, remove the plug and connect switch (or relay) contacts across the
input. Internally the sense circuit has a 10 ký pull-up resistor to +12 V. If the interlock circuit is
open, or the input voltage is less than +7.5 V, the laser will be disabled. Once the circuit is closed,
the laser will return to its previous state after a two second delay.
Emission Indicator
The emission indicator is located on the front panel of the controller and is an LED which
glows yellow when the Key Switch and Control Switch are turned to the ON positions. It does not
necessarily indicate the laser is emitting radiation, only that emission is possible.
Standby Mode
With the Control Switch (located on the controller front panel) turned to the STBY position, current
to the laser diode is turned off and the laser cannot emit radiation. More information on the Control
Switch is found in Section 2.1.2.
