Abstract: A laser machining device includes a pulsed laser generator, an accommodation chamber, a bandwidth broadening unit and a pulse compression unit. The pulsed laser generator is configured to emit a pulsed laser. The accommodation chamber has a gas inlet. The bandwidth broadening unit is disposed in the accommodation chamber, and is configured to broaden a frequency bandwidth of the pulsed laser to obtain a broad bandwidth pulsed laser. The pulse compression unit is disposed in the accommodation chamber. The bandwidth broadening unit and the pulse compression unit are arranged in order along a laser propagation path, and the pulse compression unit is configured to compress a pulse duration of the broad bandwidth pulsed laser.

Abstract: A continuous laser processing system for internal modification of transparent materials includes a pulse laser device, a scanning device, a processing platform and a control device. The pulse laser device is configured to output a laser beam. The scanning device includes a mirror group controller and a mirror group and controlled to guide the laser beam to the transparent material, wherein the mirror group is disposed at an output path of the laser beam. The processing platform is configured to carry the transparent material and controlled to move. The control device is electrically connected to the scanning device and the processing platform, and is configured to control the scanning device to form a processing trajectory at the transparent material at a scanning speed, and to control the processing platform to move at a translation speed, wherein the scanning speed is at least 20 times the translation speed.

Abstract: An optical radar includes an optical-signal receiving unit and an optical-signal pickup unit. The optical-signal receiving unit is configured to receive a reflected light. The optical-signal pickup unit is coupled to the optical-signal receiving unit and includes a first optical-signal filtering circuit and a second optical-signal filtering unit. The first optical-signal filtering circuit is configured to filter out a first interference pulse of the reflected light, wherein the first interference pulse has a first interference voltage value higher than a reference voltage. The second optical-signal filtering circuit is coupled to the first optical-signal filtering circuit and configured to generate a clock signal comprising a clock pulse; and filter out a second interference pulse that does not match the clock pulse in time point from the reflected light.
