What is Laser Terminology ?

From left to right: gamma rays, X-rays, ultraviolet rays, visible spectrum, infrared, microwaves, radio waves. Bottom: enlargement of visible spectrum from violet (400nm) to red (700nm).

The word laser started as an acronym for "light amplification by stimulated emission of radiation"; in modern usage "light" broadly denotes electromagnetic radiation of any frequency, not only visible light, hence infrared laser, ultraviolet laser, X-ray laser, and so on. Because the microwave predecessor of the laser, the maser, was developed first, devices of this sort operating at microwave and radio frequencies are referred to as "masers" rather than "microwave lasers" or "radio lasers". In the early technical literature, especially at Bell Telephone Laboratories, the laser was called an optical maser; this term is now obsolete.

A laser which produces light by itself is technically an optical oscillator rather than an optical amplifier as suggested by the acronym. It has been humorously noted that the acronym LOSER, for "light oscillation by stimulated emission of radiation," would have been more correct. With the widespread use of the original acronym as a common noun, actual optical amplifiers have come to be referred to as "laser amplifiers", notwithstanding the apparent redundancy in that designation.

The back-formed verb to lase is frequently used in the field, meaning "to produce laser light," especially in reference to the gain medium of a laser; when a laser is operating it is said to be "lasing." Further use of the words laser and maser in an extended sense, not referring to laser technology or devices, can be seen in usages such as astrophysical maser and atom laser.

What is Venus 2000 sexual stimulation

Venus 2000 (Venus II) is a sexual stimulation tool for men. The device was marketed as Venus II from October 1993 to April 1998 and since then as the Venus 2000. It is a hands free masturbation aid with controllable stroking action. The machine works with or without an erection. The creator of Venus also makes a machine for women: the Sybian.

Creation

With the assistance of Val, a Russian engineer, the Venus II was invented by Rick Gellert, President of 3S Corp. Gellert has previously written:

You may wonder how I came up with a unique product like this at all. It seems male desire for sexual activity ranges from needing an orgasm once in many weeks to wanting several in a day. Because my personal needs were greater than my loving wife's schedule would allow, I resorted to masturbation. Because using your hand can become very tiring and blase, I constantly experimented with new and different ways to have the ultimate orgasm.
I tried all of the "toys" available in adult stores and catalogs and then started experimenting with many other materials and methods. I tried all sorts of closed cell foam, soft gels, silicone, lubricated chamois and then to vacuums and water jets. I began experimenting with machines that would produce a stroke at varying speeds and after hundreds of variations, I developed a product unique enough so that I was awarded patent #5501650.
My design utilizes a part that is ultra light and allows it to stroke in any position -- up, down or sideways. The rubber liner is flexible and has a very natural feel. Venus II allows you to control the length and speed of the stroke, which stimulates you to ecstasy. I absolutely guarantee it will give you sensations and results like none you've ever had before.

Abco Research Associates has manufactured and marketed the Sybian, for women, since 1987. When Rick and Val presented their new device to Abco in 1993, they immediately recognized the outstanding concept and design; therefore, they helped them launch and market it. As a result, Abco became the primary marketer of the Venus II.

In April 1997, Abco purchased Venus II's patent along with all manufacturing and marketing rights. After a complete review of customer comments, immediately started the process of improving upon the concept. The result was Venus 2000.

Mechanics

The Venus 2000 has a gearmotor which drives a reciprocating diaphragm. Air moves to and from the outer chamber of the Receiver by a connecting hose. The amount of air in the system, or lack of it, is adjustable and determines the stroke length. Most men can adjust it to move the full length of their shaft. To use it, one simply puts some lubricant in the Receiver and place the head of ones penis to the opening. The Venus 2000 will draw the penis in when it is turned on. The user can then set the stroke length and the stroke speed to their personal preference.

Specifications

• Dimensions: 6" high, 8" wide and 9-1/2" long and weighs 11 pounds.
• Gearmotor: The unit is powered by a 1/16 HP - 15:1 ratio Gearmotor made by Bodine Electric Co.
• Diaphragm: Air is moved by a specially designed and molded diaphragm. It has the ability to push and pull air at a high speed and remain nearly silent.
• Personalized stroke-length adjustment: The V2000 has 5 internal settings that control the amount of airflow. The unit setting is based on the size of Receiver used.
• Fine air adjustment: The degree of arousal (erection) sometimes requires a fine adjustment to control the stroke length. Each V2000 package includes an air control box to make this adjustment.
