The difference is usually price, feature set, and size. An instrument typically has a front panel with knobs and button adjustments and some form of display to track how the laser diode is operating. These can all be automated with computer control via USB, RS-232, RS-485, or GPIB. An instrument is usually powered by AC, ...
An efficient laser-diode(LD) pumped Nd:YAG extracavity frequency conversion all-solid-state. quasi-continuous- wave(QCW) ultraviolet laser at 266nm was reported. The laser adopted LBO and BBO as the second and fourth harmonic generation crystals, and was pumped by three LD co nfig urations (high polarization LD, low polarization LD and low polarization LD with a Brew ster plate)in ...
The application of laser technology in the military field is basically to carry out reconnaissance and anti-reconnaissance, conventional strike, precision guidance, attitude analysis and confidential communication under the application of the characteristics of space-time and dryness with good laser monochromaticity, strong directivity and high brightness. etc. In terms of offense and defense, the offensive advantage ...
Nonlinear polarization rotation is the most common equivalent saturable absorber in fiber lasers. This technique exploits the nonlinear refractive index and birefringence effects in the fiber, allowing different parts of the pulse to accumulate differently in the laser cavity. The phase shifts, thus evolving into different polarization states, and then polarization selection by the analyzer, ...
In the medical field, holographic interferometric technology solves many problems that are difficult to solve with other technologies with its unique advantages. (1) In the diagnosis of ophthalmic diseases, laser holographic imaging technology can be used to provide three-dimensional images of the entire eye, and different positions of the entire eye image can be used ...
