594nm yellow laser pointer

Some green lasers operate in pulsed or quasi-continuous mode to reduce cooling problems and extend battery life. The announced green-light laser, which does not require frequency doubling, is much more efficient. A yellow laser pointer with a wavelength of 593.5nm appears on the market. Based on DPSS technology, two laser beams with wavelength of 1064nm and 1342nm were added through a nonlinear crystal. The complexity of the process makes the green laser pointer unstable and inefficient. The output power varies with temperature from 1-10MW, and the mode jump will occur if it is overheated or too cold. This is because the size of the laser pointer does not provide the required temperature stabilization and cooling components.
