Please post these here:

• Optics that were ordered came in
• Tested optics with laser pointer
• Mounted optics in proper mounts
• Found focal length of lens

• Found that we needed a zero degree shift mirror and ninety degree shift mirror to achieve optimal beam geometry
• Looked up prices on ebay for mirrors
• Looked up lenses for CO2 lasers on ebay and found that ZnSe is most prevalent
• Found prices for ZnSe lens on ebay
• Talked to Sinisa regarding a standardized tool mount for CNC machines
• Found prices for CNC mount on ebay
• Found prices for optics mount on ebay
• Make model of setup on AutoCAD
• Discovered that preconfigured setups for the optics for a CO2 laser are available on ebay and that they are also cheaper than assembling the setup by ourselves

• Searched for adjustable mirror mounts for co2 laser
• Found out that quarter wave is the same as 90 degree phase shift, which we mentioned before as circularly polarizing light.
• Found a laser kit with co2 laser lens,laser reflectors, laser mirrors, and laser head with air nozzle for $200.
• Used Noah's suggestion of mirror mount with 1/4 wave first mirror for $69. This will give us one mirror that has a 90 degree phase shift.
• Needed one more mirror, cheaper to buy 3 for $20 from alibaba.com.
• E-mailed distributor for dimensions on mirror mounts and laser head, and Yudi will try calling the business number later today.

• Made the check list for all the parts that need to be ordered with price.
• Made an arlternative list of parts with price as a back up.
• Sent Professor Lima the list.

• Made another alternative parts list that included mirror mounts, quantities, and specified different optics.
• Uploaded price list from alibaba.com, and an alternate price and parts list.
• Updated optics subsystem page to better reflect our current situation.
• 1/4 wave is not the same as 90 degree phase shift.

• Made sure that the mirrors and mounts had been ordered from alibab.com.
• Got the actual costs of all the parts needed.
• The alternative list will not be needed anymore.
• Talked about the things that should be covered in the paper.
