is a picture of my wood breadboard. When I was just starting in this
laser stuff as a hobby and only had HeNe's and having just learned
about all the optics equipment available, I found out about optical
tables and breadboards. I also found out how much they cost!!! Well,
since I had some pieces of really hard wood, I decided to put some of
my wood working tools to work and make myself a simple breadboard. I
drilled holes on 1 inch centers using a small drill press. Items are
generally mounted using wood screws or whatever fits. You can also see
one of my home made wooden adjustable mirror mounts. There are three
lasers on the table, a 10mw max HeNe on an adjustable jig made of wood
used for assisting in aligning the mirrors on the argons. The far argon
is a Spectra Physics 162 tuned to the 528.7 nm green line and the other
is an SP-162a tuned to the 437 nm blue line. You can just see the red
beam of the HeNe and the green beam of the far argon.
is the same setup as the picture above except with the lights off.
There is haze in the room from my working but incomplete hazer. The
digital camera just doesn't do the image justice. There's no beating
being able to see these things in action in person.
a shot looking towards the three laser beams as they are projected
towards the camera. Haze in the room helped make the beams visible as I
had to keep the power low on the argons to keep from popping my circuit
breakers. I live in an older house with really old wiring. Scary!!!
This picture came out pretty good.
this shot I've replaced the two Spectra Physics argons with my
Omnichrome 532 multiline argon. Not too much to see really except to
notice the light blue color of the multiline output from the laser. In
this image the argon was idling at only 3 lines.
here's a beautiful shot of the HeNe hitting a small bounce mirror and
the Omni 532 multiline argon being reflected towards the camera off of
a diffraction grating. The argon is putting out 7 lines at full tilt.
The dim line going horizontally to the left of the grating is the non
diffracted order from the grating. Lots of haze in the garage plus
having the camera only inches from the beam path helped make this a
spectacular shot. Notice how the HeNe's red beam is saturated by the
camera and turned yellow.
