Claim 0:
1. A laser driving device, comprising:
a laser seed (1),
an amplification and transmission unit (2),
a frequency conversion unit (3), and
a focusing unit (4),
wherein the laser seed (1) is a narrow-band low-spatial-coherence light source with a bandwidth of no more than 5 Å and configured for generating a narrow-band low-spatial-coherence laser,
the amplification and transmission unit (2) is configured for amplifying and transmitting the laser, wherein the amplification and transmission unit (2) comprises one or more amplification gain media, and the amplification gain media are plate- or sheet-shaped,
the frequency conversion unit (3) is configured for converting frequencies of the laser, and
the focusing unit (4) is configured for laser focusing;
the laser seed (1) generates a narrow-band low-spatial-coherence light, the narrow-band low-spatial-coherence light is amplified by the amplification and transmission unit (2) and is subjected to frequency conversion performed by the frequency conversion unit (3), and then the light with a converted frequency is focused by the focusing unit (4).
