Double check focus height, and try to change the velocity. Covering the glass with wet paper could also be a solution.
You need to use a low resolution (dpi) for glass to look good, the image is created by micro fractures so if you don't have sufficient spacing between points it will look blurred.
A damp paper towel on the surface can help too as it reduces the fracture size which allows a higher resolution image.
The type of glass is also a factor, cheap glass seems to work better. Avoid any crystal or thermal glass as it will shatter.
Zax.
thanks ,i will try the damp/wet paper tomorrow
what dpi you suggest ?
When we test the materials, we often set the DPI of the image 600-1200
Hope it will be help.

If you're engraving something other than a photograph, go with sand etching, for less than $100 you can go to harbor freight and get a air eraser, some aluminum oxide media, and a pressure regulator. The sand etching will look much nicer than laser. You can use sign vinyl as your masking.
I use a knife cutter, I run a sign biz but I just use a cheap $200 chinese vinyl cutter for these jobs. If you do some research there are polyester based vinyls out there instead of PVC based. The polyester ones are laser safe. I couldn't tell you which ones those are, but I'm sure if you ask around someone will know.
You probably won't like the look of lasered vinyl either I forgot to mention it melts the vinyl pretty bad. You'd be better off looking for a cheap vinyl cutter, I've seen some 24" ones on ebay for less than $200.
