There are 2 kinds of acousto optic modulators(fiber coupled aom), one is fiber coupled acousto optic modulator, the other is free space acousto optic modulator. Acousto-optic Modulator IR AOM is for IR lasers, such as 1064nm, 1550nm, and 2000nm . More about acousto optic aom modulator. Acousto-optical modulation of thin film lithium niobate waveguide devices
Acousto-Optic Tunable Filter AOTF Operation Principle The basic operation principle is explained in the following. If a sinusoidal (fixed-frequency) RF input signal is applied to the modulator, diffraction is possible only in a narrow range of optical frequencies, where a phase matching condition involving both optical and acoustic waves is fulfilled. Looking at the diffracted […]
Blue laser diodes have a wild range of wavelengths, such as 445nm, 450nm, 487nm and 488nm. 488 nm laser diode has sky blue laser beam.
Some of the Nichia Laser Diodes are easily to get , just search the module number # by google or amazon(such as ndb7a75 , the ndb7a75 or NDB7a75, when the module # is NDB, it’s nichia brand diodes ). NDB means Nichia Diode Blue, such as NDB7a75. NDG means Nichia Diodes Green, such as NDG7475. […]
