Low Resolution Laser Induced Fluorescence Experiment, Room
This experiment consists of an Argon Ion Innova 90 Laser,
the ASU001 Tunable Dye Laser and the Minilite Nd: YAG laser.
- Make sure doors to the laser laboratory (D24) are closed.
- Make sure the laser warning lights are "On".
- Make sure the aperture on the Argon Ion Laser (Coherent
Innova 90) on Laser Table #2 is in the "Closed" position.
- Make sure everyone in the room is wearing approved eye
Start Up Procedure
- Engage the circuit breaker on the east wall which is clearly
marked "Argon Ion Laser 208 volts".
- Open the two (2) water valves located near the end of Laser
- Check to see that water is flowing into the drain at the end
of Laser Table #2.
- On the remote control panel for the Argon Ion Laser, ensure
that the current control potentiometer is fully counter
clockwise and the light regulated potentiometer is fully
clockwise. Turn the key to the "On" position. Push the "On"
button and note that the "Standby" light is illuminated
- After approximately 2 minutes, the "Standby" light will
extinguish and laser action will commence when the manual
"Start" button is depressed.
- Turn on the dye circulator on the ASU001 dye laser.
- Turn the chiller to the "On" position so that the dye flows
- Place a beam stop in front of the output of the dye laser.
- Open the aperture on the Argon Ion Innova 90 laser and note
the fluorescence spot on the dye.
- Gradually increase the current on the Argon Ion laser until
the output is approximately 2.5 watts.
- The ASU001 dye laser should commence to lase at this point.
CONTINUUM MINILITE LASER
- Close the shutter on the Minilite Nd:YAG laser on experiment
#1 (low resolution LIF Beam Machine).
- Turn on the power switch on the back of the Minilite Laser.
- Activate the key on the Minilite Laser and note that the
"Laser On" light is flashing.
- After approximately 30 seconds, the "Laser On" light remains
illuminated and laser action will commence upon suppressing of
the "Start" button.
Normal operations will involve tuning the wavelength of the ASU
001 dye laser. This involves mechanically adjusting the
biorefringent filter usually under computer control. The Minilite
laser will also be fired externally under computer control.
Shut Down Procedures
1. Suppress the "Stop" button the Minilite laser. Turn the key
to the "Off" position. Turn the main power switch on the back of
the unit to the "Off" position.
Argon Ion Laser
2. Place the shutter into the closed position. Gradually
decrease the current on the Argon Ion Laser to its minimum value.
Push the "Stop" button on the remote control for the laser. Turn
the key to the inactive position. Let the laser cool for
approximately 10 minutes and turn the water off. Disengage the
main circuit breaker on the east wall of Room D24.
ASU 001 Laser
1. Turn the dye circulator power off. Turn the chiller off.
POST SPECIAL PRECAUTIONS FOR ALIGNMENT AND OPEN BEAM LASER
