Excimer laser pulse output energy up to 100 joules of magnitude, can be greater than 200 watts average power, repetition rate of up to 1KHz. In isotope separation, photochemistry, medicine, biology, microelectronics industrial processing and other aspects pumped dye laser is widely available. Dye laser is a dye laser as a laser material work. Most of the dye dissolved in ethanol, benzene, acetone and other solvents or water, dubbed 10-5-10-3M / L level concentration of the solution, the dye can be dissolved in the plastic, made of solid solution dye lasers, and even made only a few millimeters thick film laser. The salient features of dye laser output wavelength can be achieved in a large wavelength tuning range. Can be achieved using different dyes from the ultraviolet to the infrared 1.168um 320nm within the tuning, the use of frequency doubling technology, can be expanded to around 200nm. The good equipment can ensure the high output of 100mW green laser pointer.
Energy levels for generating laser transition, even if the laser level laser level under the average life expectancy than the average life expectancy is short, the introduction of a fast electrical pulses, or optical pumping conditions, it is also able to obtain this level of stimulated emission amplification. For solid-state laser material, in general, it is not possible. Gas work the optical homogeneity of the material is better, therefore, the output of gas lasers laser laser angle other than the general launch angle small. Gas lasers are generally used or electron-beam pumped gas into the pump. The main drawback is the work of active material particle density is relatively low, therefore, the device size is generally greater. The technicians are discussing the data on the drawing of green laser pointer .Sometimes with a pure gas, more gas is a mixture made with a variety of work material, which is to launch a gas laser active ions, and the rest as auxiliary gas, they can improve laser performance and output performance . Many different types of gas work material, the energy levels of the laser emission is not only a pair of generally the same time many of the population inversion between energy levels, therefore, not only many kinds of gas lasers, the laser output wavelength of very large number of almost throughout the whole from the far ultraviolet to far infrared. The warehouse of 200mW green Laser Pointer needs to be periodically cleaned.
Doped with Cr and Ti ion activation of transition metal ions made the work material, the output of the laser wavelength can be tuned; doped with trivalent rare earth elements Tm, Ho, Er work made of the material, the output of the infrared laser wavelength has been extended to (2 ~ 3um). The world's first ruby laser is doing matrix, activation of ion doped chromium ions do the work material made of laser, which was born in the summer of 1960, by the American Hughes Maiman developed. Here are two typical solid-state lasers: crystal or glass in the matrix to add transition metal and rare earth ions as luminescent centers are an important class of lasers. Ruby (Al2O3: doped Cr 3 +) is the first realization of the role of laser material, the wavelength of 694 nm, laser activation of A12O3 particles are mixed in the Cr3 + ions in the crystal. The warehouse of 50mW green laser pointer is near the subfactory.
