where did you get the coumarin dye?

[magx1]

A friend gave me a small sample.

Fantastic video, danny mcbride

Very nicely done.

yes sure you are right .... that is what i meant... but wrote stimulated....

To your question...get your self a book... e.g. f.j.Duarte "Dye Lasers"..... i will not try to persuade why a laser needs resonator nor why a car needs wheels....

First at all, ASE stands from 'Amplified Spontaneous Emission' , no stimulated as you wrote.

And, please tell me, what differences make mirrors? Resonator? So, where it resonate, at which wavelength and how?

.....go to my flickr photos. See my sets.

shaped dye cells. With such a setup, feedback does not occur with the dye cell walls. I've lased dyes in diffuse (rough surface) containers, with an overall uneven shape - I did this by placing a dye in a glass salt shaker. I've cast dyes in clear solids, lasing them in solid form without the benefit of smooth even faces to serve as reflectors. I've even lased a single drop of dye sandwhiched between a pair of microscope cover slips. See jarrodkinsey followed by dot, and com.....

Not offended at all. Just wanted to explain. Coumarin was given to me by Chemist friend - not sure of type. Due to extraordinary gain, dye lasers often have multiple transitions lasing at once. However, the light is still amplified through stimulated emission. Fluorescence is not amplified here, apart from stimulated emission. Using a grating, tuning can result in a narrow range of wavelengths. As far as feedback, it is still unecessary most of the time. I've made dye lasers using triangle -

@magx1 hey didn't mean to offend you... i've read your article in the forum and it is realy nice project. What kind of coumarin do you use? C47? if you look at the spectra that your laser emits you will see e.g. C47 that it "lases" over a range of about 50 nm.... and if you look at your laser dot you will not see any specles... so you are actualy amplifying the fluorescence of the dye and the walls of dye cell are acting like mirrors... to avoid this you could tilt your cyl. lens...
