  1600nm Er YAG Laser For Optical Communication - Laser Crylink 1600nm laser is suitable for optical communication . 1600nm is located in the safe band of the human eye . And 1600nm is located in one of the atmospheric laser transmission windows, the transmission distance is farther, the corresponding distance and resolution and speed resolution are more accurate, and the corresponding photodetector parts have high detection sensitivity. Theory of 1600nm Er YAG laser Gain medium - Er：YAG The 4I11/2~4I13/2 and 4I13/2~4I15/2 transitions of the Er3+ ion produce laser radiation in two mid-infrared bands. The wavelength of the 4I11/2~4I13/2 transition is 2.7 μm~3 μm. 4I13/2~4I15/2 can emit at a wavelength of around 1.6 μm, which can meet the needs of space optical communication and other fields. E-O Q-switch：BBO Electro-optical Q-switching is to realize Q-modulation by using the electro-optic effect of the crystal, inserting a polarizer in the cavity, and using a polarizing plate t...

Er,Yb: Glass laser glass for eye-safe laser   of 1540nm or 1.5µm to 1.6µm As an eye-safe wavelength laser, 1540um, Er3+/Yb3+ co-doped phosphate glass lasers have attracted much attention for their compactness and low cost, such as laser generation and signal amplification because the wavelength of 1540nm is just at the position of the eye-safe and the fiber optic communication window. 1540nm lasers have used in ranging finder, radar, target recognition. Er3+/Yb3+ co-doped phosphate glass cooperate with passive Q-Switch crystal -co:spinel to get 1540nm pulse solid-state laser. Er3+ emission transition occurs within this wavelength range corresponding to the 4I13/2 →4I15/2. However, Er3+ absorption itself is too weak to allow direct pumping and so, energy transfers are required. The most ef fi cient ones are given by Yb3+ ions under absorption from the 2F7/2 → 2F5/2 transition, followed by energy transfer to the 4I11/2 Er3+ level and fast nonradiative transition to the Er3+  ...

  Ho YAG laser crystal for 2100nm eye safe laser of laser ranging and medical surgery The radiationwavelength of Ho3+ ions is near 2100nm, which is located in the human eye safe band and has high transmittance in the atmosphere and has important application prospect in the fields of remote sensing detection, laser ranging, and laser radar, etc. Meanwhile, 2100nm locates in the absorption peak of the water molecule, which is highly absorbed by human tissues. When Ho laser is used for medical surgery, its penetration depth in the human body is only a few tens of micrometers, and it has little heat damage to the surrounding tissues of the human body. Therefore, it is widely used in medical surgery and treatment. Ho laser can also be used as a pump source, through the non-linear effect of crystal (such as ZGP crystal), an infrared laser with the wavelength of 3 ~ 5 mm can be realized.

Cr,Tm,Ho:YAG laser crystal for eyesafe 2.1μm laser in medical treatment, laser radar Cr, Tm, Ho: YAG Laser Crystal is high efficient laser crystal pumped by Xenon lamp or diode with wavelength of 2.1μm. the pump source main originates from the flashlamp energy absorbed by Cr3+, Ho3+ is working ion and Tm3+ acts as intermediary to transfer energy. 2.1 μm laser wave can be absorbed by water very well, transmits atmosphere easily and is safe to eye. Therefore, it is widely used in medical treatment, laser radar, military and so on. What’s more 2.1 μm laser is ideal pump source for 3-5 μm mid-infrared optical parametric oscillator.
