End of Week 3

There was a talk about buying a new laser in the AM. In the afternoon I was reading about solar pumped lasers. Overall it (solar pumped laser) sounds impractical.

This morning’s talk about buying a laser involved a discussion about the thermal properties of a crystal, which starts to act as a lens when heated. This reminded me of the LiNbO3 crystal in the LTC. If I were to rank my idea’s so far I think studying the properties of nonlinear optics is quite high. I drew a schematic for an AND gate based on polarization of light and one of the things I want to do is modulate the amplitude of the output light. Maybe I could use the LiNbO3 crystal for this. Then I could combine two of my interests into one project.

On the train I wrote a java program for adding two numbers together. It required the class Scanner.

Scanner input = new Scanner ( System.in );

That statement creates an object, input of the class Scanner.

number1 = input.nextInt();

nextInt() is a method of the class Scanner.  It expects the input to be an integer and throws an exception if it’s not.
