Basic Characteristics of Lasers
Ordinary light sources emit light in all directions. To make the emitted light propagate in one direction, it is necessary to install a certain condensing device on the light source.
The Difference Between Single-Mode and Multi-mode Fiber Lasers
Fiber laser refers to a laser that uses rare earth element-doped glass fiber as a gain medium. Fiber laser can be developed on the basis of fiber amplifier: under the action of pump light...
Wireless Laser Pointer
A laser pointer is a tool that uses a laser as an indication. Can indicate the length is far, can replace the pointer and other indicating tools, can also be used in the display of slides, such as PPT, as an indication.
Green Laser for Laser Micro Welding
Copper is a typical optional material, which can be connected to conductive parts through micro welding because of its excellent ability to effectively conduct electric energy and transmit signals.
Blue Semiconductor Laser
As metal processing technology continues to advance and user requirements continue to increase, lasers need to innovate in terms of cost and energy efficiency as well as laser system performance.
Laser Generator Elements and Classification
According to the analysis of laser generation principle, laser is under the action of "excitation source", the number of high level electrons of atoms increases, and after staying for a very short time, they jump to low level and emit laser at the same time.
Visible Spectrum Laser
White light, as we usually call it, can form a visible spectrum after dispersion through a prism. Visible light is the part of the electromagnetic spectrum that human eyes can see and feel.
Development and Application of Blue Laser Technology
Blue laser diode. The first blue semiconductor laser came out in 1999, marking that the application of the next generation of optical storage is not far away.
Red Laser Pointer and Its Hazards
Laser designator, also known as laser pointer, star pointer, etc., is the visible laser designed to be portable, easy to hold, laser module (light emitting diode) processed into a pen transmitter.
Diode Pumped Solid State Laser
DPSS laser is the diode pump solid state laser, excitation source for the semiconductor laser diode (module), laser module stimulated medium for special optical crystal solid materials...
Principles and Characteristics of Laser Modulation
Laser modulation is the process of using laser as carrier wave for modulation. Laser has excellent temporal coherence and spatial coherence.
The Difference Between Infrared and Laser Instruments
Infrared is the abbreviation of infrared ray. It is an electromagnetic wave with a wavelength of about 3.3 μ m. It can realize wireless data transmission.
Principle and Application of Infrared Spectrum
Definition and generation of infrared absorption spectrum the vibrational energy of molecules is larger than the rotational energy.
The Difference Between Fiber Jumper and Fiber Pigtail
There are many types of jumper and pigtail. The main difference between jumper and pigtail is that only one end of pigtail has a connector, while two jumpers there are connectors at each end.
Visible Light and Invisible Light
Visible light refers to the electromagnetic wave that can cause vision, and it is the part of the electromagnetic spectrum that can be perceived by human eyes.
