A new technology is imported for laser pointer

 Some technical parameters details of laser pointer should be further discussed.
Both satellite ranging, laser micro-fine processing, nonlinear optics, laser spectroscopy, biomedical, high-field optics, condensed matter physics and other scientific fields a powerful research tool. Ultrafast Laser Division is committed to providing customers with stable, high performance ultrafast laser system, the department has a number of years of work in the field of ultra-fast R & D personnel, and in the power, control and cooling so strong R & D capabilities, the National Science laser has the ability to further provide customers with more customized and high-performance products, better service, in filling the gaps to promote on the basis of potential applications of ultrafast laser market, and promote the revitalization of national laser industry. Is based on the SESAM mode-locked picosecond laser technology Amberpico series, Amberfemto series of femtosecond laser developer laser. The worker should pay more attention to technical details of laser pointer during manufacture.A new technology is imported for laser pointer
The purchase of laser pointer has the strict management requirements. Continuous mode-locked picosecond laser pulse width is compressed to ps order of magnitude (10-12s) of the "short" pulse mode-locked laser straight. According to the pump, it can be divided into continuous mode-locked lamp-pumped picosecond lasers and diode-pumped continuous mode-locked picosecond lasers; according to mode-locked, it can be divided into continuous semiconductor saturable absorber mode-locked picosecond dye laser and continuous mode-locked picosecond mode-locked laser; according to the laser medium, can be divided into solid continuous mode-locked picosecond continuous mode-locked picosecond lasers and fiber lasers. Commonly used as a semiconductor saturable absorber mirror mode-locking devices, LD-pumped mode-locked picosecond laser continuously. The so-called semiconductor saturable absorber mirror, typically using epitaxy semiconductor saturable absorber will direct growth in the semiconductor Bragg mirror, so called semiconductor saturable Bragg reflector (Saturable Bragg Reflector, referred to as SBR) or a semiconductor saturable absorber mirror (Semiconductor Saturable Absorber Mirror, called SESAM). The quality of laser pointer cannot be ensured with the technical problem unsolved.
The so-called SESAM, which is a semiconductor saturable absorber and reflector combination of new devices, when the laser incident to the saturable absorber surface, the lower level of the particles by the transition to the excited level, when the energy saturation level of the particles, the absorber will be bleached.
