Required Maintenance

Proper safeguards must be used when working with, or around the laser. The Mai Tai is a Class 4
laser that can cause serious skin and eye injury. We recommend you contact a Laser Safety
Eyewear vendor that can offer proper personal protection equipment for the tunable wavelength
outputs detailed in the specifications in your test summary.

Laser measurement equipment

The following equipment should be on hand when installing, or maintaining the
system:
• Infrared (IR) viewer, such as FJW Model "Find-R-Scope"
• A spectrometer with the appropriate software, such as Ocean Optics Model USB2000+
spectrometer with grating #H4 (600 lines/mm, wavelength range 680- 1080 nm, 400 nm
spectral range) with slit width of 25 μm and 400 μm NIR fiber with Model CC-3 VIS/NIR
opaline glass cosine corrector.
• Power meter and sensor are required to measure the laser output, such as the Ophir Juno+
USB Interface and sensor. BeamTrack series 10A-PPS laser measurement sensor is
adequate to measure the optical power.
• The StarLab application together with an Ophir meter turns your PC or laptop into a full-
fledged laser power/energy meter.

Accessory Kit

Included with the laser system is a user's manual, a test summary, a packing slip listing all the
components shipped with this order, and an accessory kit containing the following items:
• Hardware for mounting the Tsunami laser head to an optics bench.
• AC power cords and required coolant plumbing.
• System Test Summary Datasheet.

Preventative Maintenance

To keep your laser at optimal performance, the following steps should be taken approximately
every 6 months:
• Check that Millennia pump in Tsunami is making rated power at 100% current.
• To ensure pump is optimal, perform SHG temperature tuning as described in Millennia
User's Manual.
• Chiller water and filter should be changed, and air filters should be cleaned.
• Verify that the chiller is set to the appropriate temperature, and good coolant level.
Reference the Tsunami User's manual, as well as the Millennia User's manual to optimize the
performance of your system. It is recommended you read the manuals before operating the laser
system.
