No they are not. The difference is the light. Laser pens will have the red shining light while the infrared pens won't have any visible light. The only way you will be able to tell if it's working (the infrared pen) is you have to test it against either a wiimote or camera lens

Laser pointers and laser pens are basically the same thing. A laser pen is a laser pointer with a pen attached.
No, infrared and red laser are not the same. Infrared refers to electromagnetic radiation with longer wavelengths than visible light, while red laser refers to a specific color of laser light within the visible spectrum. Red laser light is visible to the human eye, while infrared light is not.
An infrared pointer uses light that is mainly in the infrared spectrum, and so is mostly invisible to humans. A laser pointer in general refers to any device using a beam of light to mark an object. Both use the same basic technology. The only difference is the wave length. IR lasers are outside of the visual spectrum where as standard laser pointers are within the visual spectrum.
The old laser printers used He-Ne laser , and the modern laser printers use infrared laser .

A laser thermometer is also often referred to as an infrared thermometer. An infrared thermometer detects the temperature of and object based on the amount of infrared radiation that is given off by said object by focusing the radiation.
Some laser pens are not dangerous indoors. A laser pen with five mW will not harm someone and is visible enough to see. But other pens which have one hundred mW are very dangerous and are a hazard.
"Laser" is a device that's used to generate very pure electromagnetic radiation,at one single frequency and with all of its photons vibrating in the same directionat the same time.Many different frequencies can be generated by different types of lasers.Infrared radiation is just one of them.
LASER diodes operate at either infrared or visible wavelengths, depending on its construction.
Generally, it's an infrared laser, although some use a visible light laser but those are generally just for playback purposes. The infrared is mainly used for burning disks as well.
Laser thermometers are actually just infrared thermometers. The laser is actually just there to make the thermometer easier to aim.
Many luxurious pens, such as fountain pens, have engravings on their outer shells. How are they made? What are the manufacturing methods? Hand-engraving, laser engraving, or CNC machining?
