The body material of green laser pointer is the brass

Through the reuse of two existing GaN diode laser (450nm wavelength for each device in the output power of about 1W), is expected to be about 50W average output power tunable femtosecond titanium sapphire laser. The laser can be achieved from a variety of imaging to spectroscopy applications such as fluorescence microscopy accessories. "Femtosecond laser is a laser over the past 20 years, science developed one of the most powerful new tools. Femtosecond pulse is so short, the current has reached 4fs less (visible - near-infrared). The package of green laser pointer is not easy to be damaged.
1 femtosecond (fs), the 10-15s, only 10 million billionths of a second, if the 10fs to measure the universe as a geometric mean of its life, but only just 1min; femtosecond pulse is so strong, multi- class chirped pulse amplification (CPA) technique to obtain the maximum pulse peak power can reach 10 terawatts (TW, ie 1012W) even beat Watts (PW, ie 1015W) magnitude, which can be focused to the intensity ratio of the solar radiation on Earth All light is focused into the tip after the size of the energy density is even higher. Femtosecond laser is completely a miracle of human creation. This kind of useful green laser pointer is good in appearance.
Past two decades, from the Kerr-lens mode-locked dye laser to a femtosecond laser Ti stones and, later, the femtosecond diode-pumped solid-state lasers and femtosecond fiber laser, although femtosecond laser pulse width and energy recorded in the constantly refreshed, but the greatest progress than an ultra-femtosecond pulse becomes a breeze. Sandia National Laboratories R. Trebino said: "Over the past 10 years, (fast) technology have been significant improvements, titanium sapphire laser and fiber laser is now to make this (femtosecond) laser operation becomes simple and and stability of this laser is now already available to buy. The green laser pointer is very popular in the European market.
And 10 years ago, but you must create. "For example, the famous manufacturer of femtosecond laser system Clark-MXR United States will produce high-power femtosecond pulses of all the components all integrated into a box, using erbium-doped fiber femtosecond laser as a seed source, with no adjustment (NO Tweak) of special design, forming the world's unique, ultra-stable, ultra-compact CPA2000 Series Titanium Gem chirped pulse amplification system does not require such a commercial femtosecond expert system to operate, can be widely used in scientific research and industrial in many areas on according to ultra-short femtosecond laser and superior features, in general, applied research can be divided into ultra-fast transient phenomenon and powerful phenomena. The body material of green laser pointer is the brass.
They are reduced as the laser pulse width and pulse energy increases to in-depth and continuous development. Femtosecond pulse laser is the most direct application people use it as a light source to form a variety of time-resolved spectroscopy and pump / probe techniques. Directly contributing to the development of its physical, chemical, biological, materials and information science research into the microscopic field of ultrafast process, and created some new research areas, such as femtosecond chemistry, quantum control of chemical, semiconductor coherent spectroscopy. Femtosecond pulse laser and the combination of nano-microscopy. The green laser pointer is very firm in the quality.
