What can laser pointers do?
Lit up 30 years ago the laser diode is the basis of all of the world's cheap lasers.A ruby laser (depicted earlier) is a solid-state laser and emits at a wavelength of 694 nm. Other lasing mediums can be selected based on the desired emission wavelength (see table below), power needed, and pulse duration. Some lasers are very powerful, such as the CO2 laser, which can cut through steel. The reason that the CO2 laser is so dangerous is because it emits laser light in the infrared and microwave region of the spectrum. Infrared radiation is heat, and this laser basically melts through whatever it is focused upon. Other lasers, such as diode lasers, are very weak and are used in today's pocket laser pointers. These lasers typically emit a red beam of light that has a wavelength between 630 nm and 680 nm. Lasers are utilized in industry and research to do many things, including using intense laser light to excite other molecules to observe what happens to them.
What does nm mean on a laser pointer?
nm is nano-meters. There will be a number preceding the nm. This number indicates how many nano-meters for a full wave length of the laser light.
Where can one purchase a green laser pointer 100mw?
You can buy cheap laser pointers online. Here is the reason: There are thousands and thousands of people searching the web for brighter, more powerful, and cheaper lasers of all colors every single day. The internet can pretty much take all of the credit for allowing this global industry to grow so rapidly. When you can connect laser manufacturers from China and Japan to distributors in the United States, the UK, Canada, and Australia; you can expect loads of people to get their hands on powerful laser pointers. Then you can see more choice for you on the internet! http://www.dinodirect.com/Electronics
Where can one buy tickets to Pink Floyd laser show?
StubHub is a fantastic website to buy tickets to Pink Floyd laser show the tickets are priced from forty-one dollars. StubHub is a well trusted website with many users.
How did Geoffrey Rose invent the laser harp?
Hi, I am Geoffrey Rose.The laser harp was inspired by the theremin, which I had built from a kit many years before.In 1976 I designed the first harp to create a digital theremin.I used a 5mw laser divided into 10 beams, which created a 5 X 5 matrix of intersecting beams in an octagonal frame.There is a pic on Laser Spectacles website.By using photoresistors at the end of the beam paths and by using AND gates diodes, 25 different sounds were produced by a synthesiser in circuit with the resistors...easy... Geoffrey Rose
Why do many laser pointers normally a red light?
because the color red draws your attention so you can see it easier and it is incredibly common
Where are lasers for sale in the UK?
There are many stockists of lasers in the UK. A good source is ebay if you are looking for a laser pointer. Another is laser pointers. Amazon is also a good source of different laser pens and pointers.
What type of laser lighting is recommended for light shows?
RGB lasers are recommended for light shows as they can produce a wide range of colors by combining red, green, and blue light. These lasers are versatile and can create dynamic and vibrant visual effects for a captivating light show.
How are light bulbs relevant today?
We use them in many things, including but not excluding: cars, lamps, microwaves, spotlights, stadiums, laser pointers, computers, diving lanterns, and projectors. They are even seen on TV or in movies (light-bulb=idea)
What property of light does a laser show clearly?
now lasers can produce many different colors, as well as well as infrared and ultraviolet radiation.
How is a laser light different from a regular light?
laser light has a constant wavelength whereas regular light is made up of many wavelengths
How many lazer pointers does it take to cach stuff on fire?
It strictly depends on the strength and power of the laser pointer/s that you are using.

How many watts of energy does the laser use?
The power of a laser is typically measured in watts. The exact wattage will depend on the specific laser being used, ranging from a few milliwatts for low-power lasers used in pointers to several kilowatts for industrial lasers.
Jane needs to choose a laptops a laser pointer and a microphone for her class the school has 10 laptops 20 laser pointers and 30 microphones how many different possible combinations are there?
The number of combinations are 10*20*30; which is 6000.
Can we see microbes through laser light?
You don't need laser light. Normal light will do, for many microbes. You DO need a microscope, since they are way too small to be seen with the naked eye.
How many frequencies and energy levels of light r in a laser beam?
A laser beam typically consists of light with one frequency (or color) corresponding to a single wavelength. Energy levels in a laser beam depend on the material and process used to generate the laser light, often resulting in coherent and high-intensity light output.
