This function will make green laser pointer more practical

 This function will make green laser pointer more practical and feasible.
But at an early stage, due to the poor performance of diode, solid-state lasers as the pump source immaturity. Until 1978 quantum well semiconductor laser concepts, MOCVD technology of the early

1980s, the use of strained quantum well lasers, the development of the LD step on to a new level. Since the 1990s, high-power LD and LD array technology, which greatly facilitate the a DPSSL

research. This article focuses on a diode-pumped solid-state lasers, first a brief introduction to the development of the LD array, and then combined with the author contact laser. All in all,

green laser pointer can be divided and classified into different types according to different standards.
Example describes the technical characteristics and development status of DPSSL devices emerged in recent years starting from the design of diode-pumped head. Diode-pumped solid-state lasers

(DPSSL) with traditional pump laser has the following advantages: 1. Long working hours. Traditional krypton lamp or xenon lamp life of only a few hundred hours, the longest not more than 2000

hours. Diode lasers for pumping life of up to tens of thousands of hours, thereby greatly reducing the maintenance costs of the user. Two. Low power consumption. Traditional lamp pumped laser

conversion efficiency of only about 3% of the pump lamp issued by most of the energy converted into heat energy, causing a great waste of energy. The LD DPSSL the issue fixed. green laser pointer

can be used in different locations as per different features and performances to meet various practical using needs and requirements. 
Next, the internal pump cladding, more outer layer of doped glass cladding of the cover, also has a lower refractive index. Structure of this fiber, multimode diode-pumped light through a composite

fiber terminal surface injection pump cladding propagation through the fiber structure, periodically through the doped single-mode fiber core and the core fiber inversion. IPG laser department (now

a branch of IPG Photonics) developed a more advanced reinforcement side parallel pumped fiber laser. It consists of an active optical fiber, the fiber and other optical components or gain stage

free fusion bonded polyhedra, so that the pump light from the multi-point injection cladding as possible. The model number of green laser pointer is ZMP005.
In this way, a simple optical output power in proportion to the zoom control to be feasible. The other side of the pump technology and V-groove coupling.
