Note: Pulsed nano-lasers are lasers that emit light not in a continuous state , but in the form of light pulses (flashing). The term is often used to switch the laser is used , which typically emit nanosecond pulses.
Depending on the pulse duration pulse energy, pulse repetition rate and required wavelength , very different methods are used to generate pulses and many different types of pulsed nano-lasers. Most laser materials are processed by "short pulse length" (or "very fast") nano-lasers. For a given laser pulse energy, the shorter the pulse, the greater the peak power of the laser.
Lasers Lasers are rays of electromagnetic radiation. Laser beams can be made from visible light, X-rays, ultraviolet rays or infrared light. Laser is a kind of excited and energetic light that is not seen in normal conditions in nature, but it can be created with special technology and equipment. Lasers differ from ordinary light in that these features give them special capabilities and applications. Laser light is brighter and more intense than light in nature . Laser light can crack the hardest metals and easily pass through hard objects such as diamonds and create holes in them. Low power and ultra-thin beams Other types of lasers can be used to perform very delicate tasks such as surgery on the human eye. Laser light can be subjected with high accuracy He took control and used a continuous beam called a continuous laser or fast blasts called a pulsed laser . Unlike ordinary light, laser light has a perfectly coordinated energy, which creates a lot of power to do different things. The word laser is derived from the initials of the words that describe its properties, which means that light is amplified by the induced emission of radiation . The difference between laser beam and ordinary light is in the important properties that exist in this beam. These characteristics are: coherence, monotony, directness of high intensity. These properties are not seen in ordinary light and these properties are used for various tasks. (Nano laser) is a laser that is on a nanoscale scale, These tiny lasers can be quickly modified and, along with small footprints , make them ideal candidates for optical computing on a chip . The intense light fields of such lasers also enable the amplifying effect on nonlinear optics or scattering (Raman) with enhanced surface area, thus paving the way for integrated nanophotonic circuits , generally Nano Laser Enhanced Nano Laser or strengthen a process in which the energy part of the electromagnetic radiation emitted by transfer and thus the optical power increases. This is the basic principle of all lasers . In quantitative terms, the increase Measures the ability of a laser medium to increase optical power.
Conclusion :
Pulsed nanocarses are lasers that emit light not in a continuous state , but in the form of light pulses (flashing). The term is often used to switch the laser is used , which typically emit nanosecond pulses.
