This could be a case of Latent Semantic Indexing. I am no expert on the algorithms search engines use but here is a defintion of LSI:
A document indexing process, used by Search Engines, that records which keywords a document contains and examines the document collection as a whole to see if any other documents contain the same keywords. LSI considers documents that have many common words to be semantically close, and those with fewer in common to be semantically distant. When an LSI-indexed database is searched it looks for similitarity values it has calculated for every content word, and returns documents it thinks best fit the query. LSI does not require an "exact match" to return useful results because two documents may be semantically close even if they don't share a particulary keyword.
In other words, an SE database has figured out that you are semantically close to things that have to do with bandwidth and since you have laser on your site and they know lazer is a misspelling (based on LSI to other pages) it somehow put two and two together and listed your site in the SE results.
You never know, maybe you can parlay this into a cash cow for people that can't spell the word lazer. Maybe you should have an affiliate link to a book called "How to Spell Good" on your site.
