Different horizontal mold cavity diffraction loss is the physical basis for the transverse mode selection. In order to improve the model's ability to identify, should try to increase the diffraction losses of higher order mode and fundamental mode, at the same time, you should also try to increase the proportion of possession of the diffraction loss in the total loss; the size of the diffraction loss and mode ability to identify value the resonator cavity and the Fresnel coefficients. Longitudinal mode selection: the general cavity, different vertical mold have the same loss, and thus the mode of identification and selection can take advantage of when the different gain of different longitudinal modes. , But also the introduction of artificial wear and tear poor.  green laser pointer  factory has won trust and support from clients by its honest reputation.4.1.1 Laser single longitudinal mode selection. Homogeneous linewidths of the spectral lines of the longitudinal mode competition (1) When the intensity of light passing through the homogeneous linewidths of the medium population inversion distribution was decreased, and the corresponding decline in gain coefficient, But the spectrum of the linear does not change. (2) multi-longitudinal mode, as shown, with q-1, q, q +1 three longitudinal mode to meet the oscillation conditions. Gradually increased as the intracavity intensity, q-1 and q +1 mode is suppressed out, only the intensity of the q-mode continues to grow, and finally into the case of curve 3. Figure 4-1 of the homogeneous linewidths of the lines longitudinal mode competition (3) At this point the light intensity Iq, G (νq, q) = the G threshold, so the oscillation to stabilize, so that the laser's internal only q-longitudinal-mode oscillation. For this  green laser pointer  company, you may get both high-quality product and service.This phenomenon is called the longitudinal mode of longitudinal mode competition, the result of competition is always closest to the line center frequency of the longitudinal mode competition is preserved. (4) in the homogeneous linewidths of the steady-state laser, stimulate relatively strong, may also be relatively weak longitudinal mode, how to interpret? This phenomenon is called the mode of competition for space. 4.1.1 Laser single longitudinal mode selection. Non-uniform broadening type multi-longitudinal mode oscillation spectrum of non-homogeneous linewidths of the lasers generally have more than one longitudinal mode. Single longitudinal mode select (1) short-cavity method: the difference frequency between two adjacent longitudinal mode?
