摘要：
一种海洋探测用712nm770nm1424nm2848nm七波长光纤激光器，谐振腔设置为四方形环形光纤激光腔，在四方形环形光纤激光腔的四个角上设置深刻蚀光纤直角反射镜，在上边光路的中间位置设置信号光λXⅠ2848nm波长周期极化铌酸锂四波混频激光谐振腔，在左边光路的中间位置设置倍频ⅠλBⅠ515nm的倍频谐振腔Ⅰ，在右边光路的中间位置设置闲频光ⅡλlⅡ1523nm的周期极化铌酸锂光学参量振荡器1，在下边光路的右段设置倍频光ⅡλBⅡ712nm的倍频谐振腔Ⅱ19，总体构成712nm、515nm、770 nm、1424nm、1030nm、2848nm、1523nm七波长光纤激光器。
摘要（英）：

The invention provides a 712nm/770nm/1424nm/2848nm seven-wavelength fiber laser for ocean exploration. A resonant cavity is set to be a square and annular optical fiber laser cavity. Deep-etching optical fiber reflectors are arranged at the four corners of the square and annular optical fiber laser cavity. A periodically poled lithium niobate four-wavelength frequency-mixed laser resonant cavity,with the signal light thereof to be lambda XI 2848nm in wavelength, is arranged at the middle position of an upper light path. A frequency-doubled cavity I, with the frequency-doubled light I lambda BI thereof to be 515nm in wavelength, is arranged at the middle position of a left light path. An optical parametric oscillator 1, with the idler light II lambda 1II thereof to be 1523nm in wavelength,is arranged at the middle position of a right light path. A frequency-doubled cavity II19, with the frequency-doubled light II lambda BII thereof to be 712nm in wavelength, is arranged at the right section of a lower light path. In this way, the above parts together form the 712nm/515nm/770nm/1424nm/1030nm/2848nm/1523nm seven-wavelength fiber laser.
