Titanium-doped sapphire (Ti3+:sapphire) as an optically pumped, solid-state laser crystal is widely used in wavelength tunable laser which tunable range is 650-1100nm, and peaking at 800nm, it is one of the widest wavelength tunable laser crystal. ength Nd:YAG laser. It is the most widely used laser in lidar at present. It can output 1064nm, 532nm and 355nm three-wavelength nanosecond laser pulses.The laser can select multiple wavelengths to work. The 1064nm band of the laser can be used to detect reflected light signal of objects on the ground, and the 5
