Diode-pumped solid statelaser radar is a pivot technology in imaging laser radar. It has advantages of small bulkand lower cost, and uses the laser with high repetition rate, high peak value power andAPD with high sensitivity. In the light of scanning method, the imaging technology can bedivided into scan and non-scan imaging. Most systems adopt direct detection method. Thelaser radar has most potential applications in the civil and military area.State-of-the-art of the diode-pumped solid state laser radar technology and itsapplications are introduced briefly in the paper. The applications include preciseguidance, wind velocity measurement and helicopters collision-avoidance. Some of the keytechniques are outlined on the basis of several typical laser radars.
