The battery of green laser pointer

It has excellent optical quality and near diffraction limited beam angle, of course, easy to manufacture glass, and can be a good optical polishing. Ions in the glass laser fluorescence line width is usually higher than the width of the crystal, the reason for the lack of good single active atoms only crystalline environment, so the laser glass laser crystal laser thresholds than the high school addition, the thermal conductivity of glass rate is much lower than when the vast majority of the crystal matrix material + glass laser rods with high average power operation, low thermal conductivity caused in the holding of a large number of thermally induced birefringence and optical distortion. The customer can customized one or several optional functions ofgreen laser pointer.
Has been used in the glass away from the laser generated in a N spear ten, Yg, ten, E ten, T X and H +, the first section will discuss N x.3.2 spear ', erbium-doped glass is particularly important because it of 1. 55} txr radiation does not penetrate the human eye lens, it will not damage the retina due to bait the three-level features and Er `} ten pairs of pump light absorption is small, so as to be satisfied with the system efficiency Chin and the German people must be mixed in such a technical process called sensitization, the amplified ion or ions do not absorb the laser's wavelength absorption of radiation, and later in the ion pump laser radiation, the energy band, or its directly transmitted to the laser excitation energy ions, due to Nd3}-Y63}-Erg +: glass with three-level system work, so its efficiency is at least more than one order of magnitude lower laser glass chin. The wholesale price ofgreen laser pointercan be provided if the quantity is large enough.
Since the emergence of the ruby laser has been studied a lot of matrix material, as opposed to glass, crystal matrix of the advantages of laser generally reflected in a higher thermal conductivity, fluorescence spectrum is narrow, and sometimes greater hardness. However, the crystal matrix material doped optical quality and uniformity is often worse than the glass, the absorption lines are usually narrow potential about laser crystals comments, please refer to the literature. Gemstone first discovered the laser material (ruby laser) to Sapphire as a substrate material sapphire) substrate is very hard, high thermal conductivity, easy incorporation into the transition metal to replace Al. Al position is too small for the earth, not the high concentration of rare earth impurities braced sapphire addition to today still Use the ruby, the Chin-doped sapphire laser as a tunable material, has won its importance. The coupon ofgreen laser pointercan be used in the promotion ofgreen laser pointer.

Unfortunately, this material appeared on the market after two years disappeared, YAP drawback is less efficient than expected, and performance is unstable. The OEM production of green laser pointer has high requirements for the equipment the manufacturer uses.
