The diode-pumped 589nm Yellow laser Pointer are based on our proprietary laser cavity technology. This new technology allows our yellow lasers to operate in TEM00 mode with extremely low power consumption in compact laser housing.
589nm laser has great application on optical spectrography, laser allocation & guidance, astronomical observation and so on. Astronomical observatories use this wavelength in higher power to illuminate sodium particles in the upper atmosphere while they calibrate the orientation of their telescopes and optical devices.589nm 'sodium' wavelength appears more gold in color compared to the more amber appearance of the 593.5nm wavelength. This yellow laser pointer is closer to the middle of the spectrum, making it brighter to the human eye. It will be your best yellow laser you ever had.
