1.What is Co: Spinel? Cobalt spinel, chemical formula Co: MgAl2O4, spinel is a hard, stable crystal that polishes well. Cobalt conveniently replaces magnesium in spinel without the demand for added charge-compensating ions. Easy Q-switches or saturable absorbers generate high-power laser pulses without the use of electro-optic Q-switches, reducing package dimension as well as eliminating high-voltage power supplies. Co: Spinel has actually been revealed to be a really reliable passive Q-switch for producing 1.2 µm - 1.6 µm lasers. Co2+ turned on MgAl2O4 (Co: MALO, Co: spinal column) can be made use of as a tool for passive Q-switching of lasers running in the 1.3 - 1.6 µm spectral variety. Instances are 1.32 µm and 1.44 µm Nd: YAG lasers, 1.31 µm iodine lasers, and also particularly 1.54 µm erbium glass lasers. The adequately high absorption cross-section of the Co2+ ion as well as the functional lack of excited-state absorption make this product an extremely reliable passive Q-switch (without the requirement for intracavity) for numerous sorts of erbium glass lasers, including diode-pumped integrated circuits. emphasis). Negligible excited-state absorption leads to high-contrast Q-switching operation with a ratio of initial (small-signal) to saturable absorption higher than 10. 2. Features of Co: Spinel. Reduced optical losses in the wavelength range of 1,3 µm - 1,6 µm. The high laser-induced damage threshold. 3. Application of Co: Spinel. Shuffle is an easy emitter of passive Q that can be utilized for semiconductor switching security lasers operating at the human eye wavelength of 1.5 μm. Because the 1.5 μm transmitter is suitable for the industry initially as a result of the application of the 1.5 μm medium-wavelength waveguide, so in the case of this wavelength, as well as some sensitive eyes are sensitive. (Ge and also InGaAs photodiodes) accessibility. Easy Q-switch for Emergency Room: Glass @ 1.54 µm. 4. Benefits of Co: Spinel. Cobalt-doped magnesium aluminate spinel (Co: MgAl2O4) can generate brief nanosecond pulses with high peak power around the eye-safe wavelength of 1.5 μm, making it excellent for telemetry applications. It has the advantages of high absorption area, lengthy service life, uniform cobalt distribution, and absorption bandwidth.
