Energy transmission within the laser pointer structure
An ordinary laser pointer can transmit sound up to 100 miles in the air. If the excited substance is placed in the resonant cavity, the light radiation reflects back and forth along the axis in the resonant cavity, passes through the substance many times, and the light radiation is magnified many times to form a beam "laser" with high intensity and concentrated direction. This is the laser oscillator. Under the witness of more than 200 enterprises and more than 800 guests from the upper, middle and lower reaches of the industrial chain, the laser industry fund with a total amount of 5 billion yuan was officially announced and signed on-site. This is currently the largest laser industry fund in the country. It is reported that the fund was initiated and established by the green laser pointer Industry Branch of the China Small and Medium Enterprises International Cooperation Association, Chushang Capital Group, and Ping An Bank. Laser technology has the potential to completely change people's lifestyles. Technologies like laser rapid prototyping (3D printing) are transforming manufacturing and inspiring creativity. Lasers transmit energy for UAVs over long distances.

Laser surface denaturation is the use of high-power lasers and material properties to change the surface properties of components. If necessary, give the laser surface resistance to friction (normal temperature or high temperature), fatigue resistance, and corrosion resistance. Due to the identification of the metallurgical industry, we have developed laser nano-ceramic alloying, high power laser pointer denaturation enhancement technology (laser quenching), laser melting and covering repair technology. The brightness of a laser source is a measure of its output power and beam quality. Essentially, it is the laser power divided by the BPP. Therefore, its unit is W/cm2, and for clarity, the laser diode is at the edge emitter. Other common laser types, including vertical cavity surface emitting lasers (VCSEL), strip/stack, array or quantum cascade lasers (QCL), are not in our discussion due to their obvious deviations.
