Laser pointers can accomplish the same task using silicon nano materials, in the 600 nm high, and there are hundreds of different diameter of nano materials on the.High powered laser pointer column has a thousand points. The nano light travels at a smaller diameter point to either nano nano dots of larger diameter to be fast, high powered laser is controlled by the nano width can be path to allow engineers to fine tune the light path through the artificial planar structure to create the entire surface of the lens.
Early in the blue laser pointers image by using nano dot experiments in lens edge blur, like a magnifying glass. However, the two artificial structure plane coupled together, the side direction of the nano structure, the engineers can create a strongest laser pointer, can capture from the scope of the 70 degree angle and focus light, laser show for the first time to be used in the microscope and green light laser applications.
In this case, in the required range of the spectrum can be broadly tunable laser pointers.High powered laser pointer technology is the key to successful detection especially the rapid development of quantum cascade lasers, high sensitivity, high selectivity for trace gas detection provides the main advantages of an effective way of.High powered laser is a spectral tuning range very wide, to have a wide absorption band of mixed gas detection at the same time possible.
Ringdown signal from strongest laser pointer to lens refrigeration, detector cavity ringdown signal by the sampling card and laser show, and get the ring down time by fitting a single exponential function, green light laser of the gas absorption coefficient, and calculate the gas concentration.
