High Power Laser Weapons and Their Cooling Systems
[in Chinese], [in Chinese], [in Chinese], [in Chinese], and [in Chinese]
The categories and developments of high power laser weapons were reviewed. The possible thermal management methods for high power laser weapon were summarized according to the heat loads of available cooling techniques. For the cooling of kilowatt solid lasers, laser diodes pumping method can be adopted to reduce heat The categories and developments of high power laser weapons were reviewed. The possible thermal management methods for high power laser weapon were summarized according to the heat loads of available cooling techniques. For the cooling of kilowatt solid lasers, laser diodes pumping method can be adopted to reduce heat generation in the gain medium, and the microchannel liquid cooling or spray cooling method can be used to effectively dissipate heat from gain medium. For the cooling of megawatt class chemical lasers, e.g., chemical oxygen-iodine laser or mid-infrared advanced tritium chemical laser, the spray cooling method or heat pump loop are generally concerned..

Ultraviolet Laser and Its Application in Laser Processing
[in Chinese], [in Chinese], [in Chinese], [in Chinese], [in Chinese], and [in Chinese]
The advantages of ultraviolet(UV) laser include short wavelength, concentrated energy, high resolution, especially its "cold processing" properties. The UV laser can destroy the chemical bond of matter directly but not give rise to external heating, and become an ideal tool for processing fragile material. ItThe advantages of ultraviolet(UV) laser include short wavelength, concentrated energy, high resolution, especially its "cold processing" properties. The UV laser can destroy the chemical bond of matter directly but not give rise to external heating, and become an ideal tool for processing fragile material. It is able to carry out drilling, cutting and ablating on various materials, and it has a wide application in the field of micro-machining. The fundamental principle, main characteristics and development of several UV lasers are introduced, and the application of UV laser in laser processing are also analyzed..

Recent Progress of Low Loss Photonic Crystal Fiber
[in Chinese], [in Chinese], [in Chinese], and [in Chinese]
It is well known that loss is an important parameter for both conventional fiber and photonic crystal fiber(PCF). The loss of index-guiding PCF was 240 dB/km in 1999, with the development of fabrication technology, the loss has been reduced rapidly. It is only 0.28 dB/km at 1550 nm wavelength for index-guiding PCFs, whIt is well known that loss is an important parameter for both conventional fiber and photonic crystal fiber(PCF). The loss of index-guiding PCF was 240 dB/km in 1999, with the development of fabrication technology, the loss has been reduced rapidly. It is only 0.28 dB/km at 1550 nm wavelength for index-guiding PCFs, while it is only 1.2 dB/km at 1620 nm wavelength for photonic bandgap PCF. Based on the analysis of loss origin of conventional optical fibers, the loss mechanism of PCFs has been introduced. After analysis of the parameters of conventional fiber and PCF, several ways to reduce the loss are proposed..

Preparation of Titanium Dioxide Films by Laser Chemical Vapor Deposition Method
[in Chinese], [in Chinese], [in Chinese], [in Chinese], and [in Chinese]
Rutile TiO2 films and rutile-anatase-mixed TiO2 films were prepared by Laser Chemical Vapor Deposition at laser power between 0 to 200 W and at substrate pre-heating temperature between 400 to 700℃ at the presence of O2.
