Back to Items of Interest Sub Table of. This chapter represents a potpourri of general laser information. Basically. when something interesting and relevant to lasers shows up on one of the. USENET newsgroups or elsewhere, it gets stuck in here. Therefore, given the. As always, I welcome contributions to help expand quantity and. Topics not covered here may often be found in the chapters on specific lasers. For example, information on mode structure and coherence length is in the. Helium Neon Lasers, specifically. Longitudinal Modes. Here are meanings of a few acronyms and abbreviations commonly used with. More will be added as I think of them or am reminded. For the most part, I explain such terms when first used in a given section. AR Anti Reflection coating. The coating on an optical surface to. This produces the blue or purple. Both surfaces of the OC see below mirror of a laser may be. AR coated though you cant detect this on the inner surface which also has. OC coating. HR High Reflector mirror or High Reflection coating The totally. HT High Transmission Coating. Probably similar to AR coating this. OC Output Coupler The optic that couples the beam out of a laser. Usually, this is the partially reflecting output mirror of a laser. The OC reflectivity and spectral response will depend on the type and size. Santa Claus In Trouble-. However, for. some lasers like green DPSS types, the optic from which the beam emerges. HR mirror for the fundamental wavelength and the actual. However, I still consider the mirror. Dielectric mirror or coating A surface built up from multiple. These are also called dichroic. Dielectric mirrors can have nearly perfect 1. Note that throughout this document, I use the term dielectric in reference. Nowadays, it apppears as though. CW Continuous Wave. A laser that operates with a constant output. The opposite is a pulsed laser which produces short. A Quasi CW laser. W Watt. A measure of power electrical, optical, mechanical equal to. W is kilo. Watt 1. W, m. W is milli. Watt. 1. 0 3. W, u. W is micro. Watt 1. W, n. W is nano. Watt. A few on line references with just a bit more extensive information can be. And, of course, general on line encyclopedias like. Since laser and optics deals with units on scales from the very small to the. I couldnt figure out a better place to put them, here are.

The u should really be the Greek symbol for micro but Im too lazy to use. HTML code. They make a big deal out of the special case of kilogram which is the only SI. So, the SI police will come get you if you write something. Luxpop has calculators for a variety. Gaussian beam propagation. Back to Items of Interest Sub Table of. Laser Power, Photons, How Much Light, Beam Profile. Any given laser be it a He. Ne, argon ion, CO2, or other CW laser or a pulsed. Nd YAG, Ti Sapphire, or excimer, will have two, maybe three. The manufacturers power rating based on model. This is the one you find. For He. Ne lasers, there is a single rating since these are generally. Example. Spectra Physics He. Ne laser model 1. He. Ne laser 5 m. W. For CW lasers which have variable output power like argon ion and CO2. Example See the chart in the section. ArgonKrypton Ion Laser Tube Life. Similarly, pulsed lasers like flashlamp pumped Nd YAG may have a chart of. However, note that pulse to pulse variations of 1. The actual measured power output at the time of manufacture. This value. or chart may be provided with a certification document or hand printed. As the laser gets. Example for the Spectra Physics model 1. He. Ne laser 6. W. The CDRH sticker rating. This is the MAXIMUM power rating for the. CDRH designation. However, a much higher. A He. Ne laser produces its maximum output power at the nominal operating. Example for the Spectra Physics. He. Ne laser 1. W Max, Class IIIb Laser Product. Where the output power of a laser increases with increasing tube current. Unfortunately, when people offer used or surplus lasers for sale, they often. CDRH sticker rating a because it is the only one that may be. HIGHEST and sounds more. See the section Buyer Beware for. Laser Purchases. Here are those definitions you always wantedPortions from Dr. Mark W. Lund mlundmoxtek. A Lumen is a quantity of light, the same kind of unit as a watt, but. If you are looking at the specification of a light source Lumens are the. A Lux is a lumen per square meter, which we might call illumination. It is how much light that. A Nit is a lumen per square meter per steradian, which we might call. If a Lux of illuminance. Nit of luminance. A Candela is a lumen per steradian. It is used for point sources. Put another way, Candelas are a measure of luminous intensity through an. For an isotropic. Candela is equal to 1 lumen per steradian. There are 4 x pi or. A 1. 2. 6 lumen. isotropic source would then produce 1 Candela. This doesnt really apply to. However, it is still possible to define the Candela. So, if your laser put out 1 lumen over. Candelas would be 1. Candelas. I Mark was at one time a true expert on photometry and radiometry and I still. LED with another because every company. Warren Smith gives an admirable discussion of photometry in his book Modern. Optical Engineering. Or, check out the Lighting. Design and Simulation Glossary for definitions of these and other related. A Radiometry versus. Photometry FAQ by James M. Palmer jpalmerazstarnet. FAQs are ever fully developed. PDF Version also. From Ian Ashdown byheartdirect. A foot candle is a unit of illuminance, which is defined in ANSIIES. RP 1. 6 1. 99. 6 Nomenclature and Definitions for Illuminating Engineering, from. Illuminating Engineering Society of North. America as The areal density of the luminous flux incident at a point on. In plain English, illuminance is the quantity of light arriving at a. The point does not have to be located. One foot candle is equivalent to one lumen per square foot where a lumen. A wax candle flame has a luminous intensity or equivalently, candlepower. If you hold the candle one foot away from a. It will be 14 fc at. Brightness is a psychophysiological phenomenon that cannot be measured. The term photometric brightness used to refer to luminance, but. Let me rephrase that it. There is an understandable but technically accurate description of photometric. From Don Klipstein donmisty. A lumen is defined as the luminous flux of 16. Terahertz, or a. wavelength of approx.
