    Wavelength Guide

    For now I have included:

    • Diode (Mainly all CW and room temperature, but with a few exceptions.)
    • DPSS (Have focused on recorded research and commercial lines, as there are far too many combinations that could exist in this category.)
    • OPSL (Commercial lines, similar story with DPSS's if fully explored.)
    • Solid States
    • Gas
    • Metal Vapour

    I was going to include dye lasers, but they are widely tunable and can cover a large portion of visible spectrum anyway. I might as well colour that combined spectrum in all together otherwise.

    I plan to make this thread more comprehensive over time. The idea I have is that one day a member can have a specific wavelength in mind, and then come here to find out about it and answer some keys questions such as:

     What mediums are available in that wavelength?

    • Diode (including semiconductor chemistry)
    • DPSS (Syntax: Laser Harmonic (SHG etc); [Wavelength to 1dp.]; (Laser crystal ; NLO crystal) [Wavelength Process]
    • OPSL (Follows similar syntax to DPSS)
    • Solid State (includes wavelength to 1dp and medium)
    • Gas (includes wavelength to 1dp and medium)
    • Metal Vapour (includes wavelength to 1dp and medium)

    What is the commercial availability like?

    • DIY/Research Only (only seen in research articles, or in homemade attempts)
    • Request/Order based (Not accessible without contacts)
    • Limited availability (Sparse amount of sources available)
    • Widely available (Readily available)

    What power levels are available?

    • Low (Only seen <5mW)
    • Moderate (Anything between 5-200mW)
    • High (Available at >200mW)

    How much does that wavelength cost?

     As the major population of LPF is US situated. I will base the price range on USD. I am using the cheapest available way of getting hold of that medium at that wavelength. Obviously, if you are after a higher quality/higher power unit then it will easily make it into another price range. I will also not list exact prices as these change based on several factors mainly due to availability or suppliers catching on to our interest.

    • Inexpensive (<$50)
    • Affordable ($50-$200)
    • Costly ($200-500)
    • Expensive ($500+)

    How available is this wavelength?
    • Wide Availability
    • Limited Availability
    • Request/Order Only
    • DIY/Research Only

    If the availability is limited or request based, I will list the most suitable sources of where you can get hold of them. If widely available, then there is no need for me to list a source, as a simple search of Google will help you find them.

    ------------------------------------------

     Also for a more comprehensive list of diodes available, please direct yourself to jnrpop's thread. --> List of Diodes

     Due to the excellent work done by jnrpop, there is no need for me to list every diode. Instead I will list noteworthy options.

    Update: Added main body text, and now features new HTML features for thread enhancement. Directly viewable and interactive on devices 700px+. Auto detecting CSS styling included to provide redirect link for those under 700px, such as of mobile devices. External webpage has better capabilities on lower screen sizes.

    Edit: Landscape mode on mobiles may be able to get around the iFrame 700px problem.
