Abstract
A laser beam combining device includes three lasers, a polarizer, and a mode converter. The second laser device, the mode converter, and the third laser device are located on a first straight line in that order. The polarizer intersects with the first straight line at an imaginary joint point. An included angle between the first straight line and the polarizer is about 45 degrees. The polarizer and the mode converter are positioned between the second laser device and the third laser device. The polarizer is adjacent to the second laser device. The mode converter is adjacent to the third laser device. The first laser device faces the polarizer and is located on a second straight line perpendicular to the first straight line and passing through the joint point. The three laser devices emit TE mode red, green and blue laser beams, respectively.
