Variables for laser equations

  1. May 14, 2014 #1
    1. The problem statement, all variables and given/known data

    i need a pdf or a homepage where i can get all symbols (variables ) for Laser questions
    for example
    ω=Beam waist
    Q= quality factor

    i have a problem understanding some questions because i dont know which symbol they represent
    i hope you can help me

    thank you very very much
    2. Relevant equations

    3. The attempt at a solution

    I would be surprised if there is a single site with all the symbols you will ever encounter.
    Particularly, some symbols may have different meanings in different contexts.

    Perhaps you will be better served just to show us the problem and ask about the symbols you don't know about?

    You can usually work out what some of the symbols should be by relating the equations to the description of the situation.

    Thank you for your answer
    I cant post every question i have because i have many questions

    I hope i could find something that can help me out of this problem
    Today i searched one hour to find the equation for Coherence time and Coherence length and finally found it in my books

    Anyway i have to make my own equation list.

    As it seems there isn't any homepage to solve my problem

    Certainly no single page ... the main trouble is that your needs are too vague.
