What is a acousto-optic modulator AOM modulator
What is a acousto-optic modulator AOM modulator Acousto-optic modulation is an external modulation technique. Generally, the acousto-optic device that controls the intensity variation of the laser beam is called an acousto-optic modulator (AOM modulator). The modulated signal acts on the e...Read More -
What is a narrow linewidth laser?
What is a narrow linewidth laser? Narrow linewidth laser, The term “line width” refers to the spectral line width of the laser in the frequency domain, which is usually quantified in terms of the half-peak full width of the spectrum (FWHM). The linewidth is mainly affected by the spontaneous radi...Read More -

How to choose the type of optical delay line ODL
How to choose the type of optical delay line ODL Optical Delay Lines (ODL) are functional devices that allow optical signals to be input from the fiber end, transmitted through a certain length of free space, and then collected at the fiber end for output, resulting in time delay. They can be app...Read More
