It was a cold day and already dark. I just
run my motor bike to home after a day work. It was such a cold day that makes
me feel lonely and need person to chat to warm my heart. You may understand my
feeling, an alone girl without boy friend to show a loving care for me,
especially in such a cold day. Gosh, don't make myself fall into such emotion. Just
call a friend and save myself. I call my best friend, Huffy. We are university
schoolmates, live in one room. After graduate, she work in another county so we
only contact by phone and mail, haven't seen for a long time, but she always
comprehend me very much. We chat for a long time, ask about work, life and her exam
that makes me feel better. Suddenly I saw a shining green beam lying in the
sky. The light source is ahead of me in a long distance. I described to Huffy
about it and she wondered about it. We just hold on the call and I riding to
the beam. It is a laser pointer. To tell the truth, I haven't hear about it
before. In our country, there are also lasers but they are low power in general
and equipped on toy weapon.
Therefore, it only releases weak beam or even no
beam but a shining spot. It is my first time seeing a real laser pointer. I
walked close to it and observed for a while, at the same time, I described it
for Huffy. She said she has not seen such things before, either. The beam is
brilliant and thin. There are also large amounts of finely ground particle
among the beam. The holder told me that is the suspended particles in the air. He
also introduced that if it were in a vacuum environment or just pure air, the
beam will more pure. However, in an amateurish sight, the flaring particles
make beam more beautiful.
Huffy was very considerate and told me just
enjoy it. She is such a good girl and understands me very well. I do need time
to see the laser earnest. The curiosities drive the chill away. I consulted to
laser holder about the details. He was enthusiastic to explain for me. His name
is Yale. I wondered how long this beam is. I just couldn't see the end of it,
it already insert deep in the night sky. Yale explained for me in patience that
his laser is a 50mW laser pointer, which is able to exposure to 2000m away in usually
environment, and will longer in a clean environment. That is amazing, I just
saw that it is hi-power even beat to star. Yale said it is because of endpoints
and human limited vision. Moreover, he told me other things such as the color
and wavelength. He collects all sorts of color laser pointers. At last, he
invited me to play with him and other laser amateurs.
That was sweet and I do need concentrate on
some new hobbies but not the boring mood.
Laser pointer is a magical thing that can
make me happy. The light world makes my living world energetic.
This unexpected case makes my home way
shorter and warmer. Thanks to Huffy and Yale.
