Embodiment Construction

[0041] Specific embodiments of the present invention will be described below with reference to the drawings.

[0042] Figure 1a Shown is a functional block diagram of a seed light injection system 100 according to an embodiment of the present invention. The seed light injection system includes a seed light source 110 , a driving circuit 150 , a beam shaping component 160 , a driven laser 120 (also known as a controlled laser oscillator), and a pumping source 130 . The seed light source is driven by a drive circuit 150 that provides radio frequency modulation current, and emits a photon beam 191 with a continuously scanned wavelength, which is injected into the slave laser 120 after the beam is shaped by 160 . The slave laser is excited by the energy flow 193 generated by the pump source 130 to achieve population inversion. Different from the prior art seed light injection system which must adjust the cavity length of the slave laser in real time through the cavity length st...

Abstract

The invention discloses a seed light injecting master-slave matching method comprising the following steps of: generating seed light the wavelength of which is continuously scanned; injecting the seed light the wavelength of which is continuously scanned into a controlled laser oscillator; continuously scanning the wavelength of the injected seed light, wherein the scanning range covers longitudinal dies of one or more controlled laser oscillators; establishing population inversion by the controlled laser oscillator under the action of a pumping source and generating a stimulated radiation source; and outputting laser with the wavelength being equal or close to that of the injected seed light, wherein the mode matched with the wavelength of the injected seed light in the stimulated radiation gets the upper hand. According to the invention, the injection signal the wavelength of which is continuously scanned is generated by the seed light source, the length of the light cavity of the controlled laser oscillator can freely fluctuate without being controlled and the master-slave matching can be realized dynamically, so that the invention has the advantages of simple structure and low cost and is easy for operation.

Description

technical field [0001] The invention relates to a seed light injection master-slave matching method, in particular to a non-invasive seed light injection master-slave matching method. The invention also relates to a seed light injection system using the method. Background technique [0002] In laser output devices, seed light injection technology is often used. The seed light injection technology uses a low-power and high-stable seed light source (or master laser) to control the power oscillator (or slave oscillator) to achieve the purpose of purifying the output spectrum, stabilizing the output frequency and shortening the start-up time. , military, scientific research and other fields have a wide range of applications. Oscillators not injected with seed light start up randomly, creating output patterns in competition. After the seed light is injected, the mode close to the wavelength of the seed light has an absolute advantage at the beginning, so that the output mode c...
