MaiTai laser:
Turning on the system:
1. Verify the all connectors are plugged in to the power supply.
2. Verify that the chiller reservoir is full.
3. If the chiller was turned off, turn it on and verify that it is set
to 21 0C
4. Turn on the power supply power switch.
5. Turn on the power supply keyswitch.
As the system starts up, the following message sequence is
displayed on the power supply LCD screen:
“Spectra-Physics” (followed by the software version
number)
Then self tests 1 through 12 will complete, and end with:
“Success. Boot test passed.”
Wait about 40 minutes for the power supply LCD screen to
indicate “100% warmup”, which indicates it is ready for use.
6. Turn on the host computer, then start the control program. The
Com Port Setup menu will appear first.
7. Verify that the port setting is 2 based on our system, then
press OK.
8. Verify the humidity in the information menu should be under
10% for normal operation.
9. Wait until the status line on the Main menu says “Ready to
turn on”, then turn on the laser.
10. From the Main menu, set the desired wavelength.
11. The PULSING indicator on the Main menu will turn green
when pulses are detected.
12. Open the shutter.
13. Output power should reach maximum output within 30
minutes.
Turning off the system:
1. To temporarily turn off the laser emission without turning off
the laser, click on the SHUTTER button. Emission will stip
immediately and the SHUTTER light will turn gray. However,
the EMISSON light will remain on to warn of possible
emission. To resume operation, open the shutter again by
clickling on the SHUTTER button.
2. When done using the laser, click the SHUTTER button, and
SHUTTER will turn gray. Then click the OFF button to turn
off the laser. The laser will turn off immediately, as will the
EMISSION light.
3. If you are done for the day and wish to turn off the computer,
click the QUIT button to exit the control program, then turn
off the computer.
4. Turn the power supply keyswitch to OFF. TO minimize
start-up stabilizing time, leave the power switch in the “ON”
position and leave the chiller on. (day-to-day operation_
5. If the laser is not to be used for an extended period of time,
turn off the main switch on the power supply, and then the
chiller.
Warning: The chiller must always be on when the
MAITAI power supply is on, even if the diode lasers
are not switched on.
Wavelength Extension Unit (WEU-02):
1. After open the SHUTTER button in Maitai control program,
the laser will go through the WEU immediately.
2. Set a power meter in the output port of WEU to measure the
pump and Stokes light.
3. Adjust the “MPE” MIN/MAX thumbwheel control to set the
pump power to about 40 mW.
4. Slowly turn the “power to fiber” thumbwheel control to
maximum position to get maximum power for Stokes, which
is about 60 mW.
Warning: Before turn off the SHUTTER button in
the MaiTai control program, the thumbwheel controls
for pump and Stokes should be adjusted to the
minimum position to protect the high nonlinear fiber.
Olympus BX61 microscope:
Turn on:
1. Switch on the central power and then start up the PC.
2. Enter the user name and password to log on to the windows.
3. Double click the Fluoview software to start up.
4. Unblock the laser path to the microscope.
Turn off：
1. Set all the parameters you changed during the operation to
initial conditions and close the software.
2. Switch off the central power and then the PC.
Operation:
Please be fully trained and refer to the manual for the detail
operation.
Spectrometer:
1. Turn on the power to the spectrometer and set the fiber
detector for the scattered light you want to measure.
2. Open the software and start to get spectra from the scattered
light.
Warning: Don’t directly measure the laser, the CCD
will be over-exposure and damaged.
