Abstract
Official abstract text for this publication.
A laser radar system includes a first light source unit including a signal light source—a seed laser diode or a light source for amplifying a laser beam from the seed laser diode—and a pump laser diode, a second light source unit disposed to be spaced apart from the first light source unit, the second light source unit including an optical amplifier for amplifying a signal output from the first light source unit, and an optical connector for connecting the first light source unit and the second light source unit to each other, wherein the second light source unit is disposed at an end of a laser transceiver unit of the laser radar system.
First claim
Opening claim text (preview).
What is claimed is: 1. A laser radar system comprising: a first light source unit including a seed laser diode, a first pump laser diode, a second pump laser diode, and a first optical amplifier connected with the seed laser diode and the first pump laser diode; a second light source unit disposed separately from the first light source unit, the second light source unit including a second optical amplifier configured to amplify a signal output from the first light source unit, and a transmitter and a receiver separated from each other, wherein: the second optical amplifier is connected to the first optical amplifier and the second pump laser diode through an optical fiber, and the second light source unit is disposed at an end of the transmitter. 2. The laser radar system of claim 1 , wherein the transmitter includes a pulse laser generator and an optical deflector, and the second light source unit is coupled to the pulse laser generator disposed at an end of the transmitter. 3. The laser radar system of claim 1 , wherein the receiver comprises a light receiving lens and an optical detector.
