== Equipment == Diode data sheet: [[File:NDB7A75.png]] Water blocks: [[File:waterblock.pdf]] Crystal base: [[File:9081g.pdf]] == Cavity Geometry == == Alignment Procedure == # Set up the HeNe so that isit intersects some point at the cavity folding angle (relative to a line of holes on the table). At that point, place the center of the first curved mirror. # Angle the first curved mirror so that the beam travels straight along the hole line. # Place an iris along the HeNe path after the second HeNe mirror but before where cavity flat mirror will be set up. Make sure the beam passes through the iris when almost closed. # Place the output coupler at the desired distance for the long arm. Use the iris from step 2 to make sure it retroreflects the beam precisely. # Place the flat mirror at the short arm distance from the first curved mirror. Use the iris to align the retroreflection from the back of the mirror. == Things to Try == Remove short arm flat mirror and align blue along hene/780 Mode match 780 and look for interference at the output
