    摘要: A PA section (3) of a fiber laser device includes: an amplifying fiber (4); an LD (5) for exciting the amplifying fiber (4); an LD heat sink (6a) that absorbs heat generated by the LD (5); and an LD fan (7a), a thermistor (8), and a CPU (9) that control a heat resistance R th of the LD heat sink (6a). A temperature of the LD (5) is controlled to approach T peak by changing the heat resistance R th of the LD heat sink (6a), where T peak is a temperature at which a lasing wavelength of the LD (5) equals a wavelength at which an absorptance by the amplifying fiber (4) peaks.

    摘要: Disclosed herein are architectures for an external cavity laser. In some embodiments, the external cavity laser includes vertical cavity surface emitting laser (VCSEL) elements, a Brewster plate, frequency doubling chips, and a microlens array. The Brewster plate is arranged at an angle relative to the light path, and is configured to polarize at least the light received from the VCSELs and propagating on the light path in a first direction, and extract, from the external cavity, frequency-doubled light propagating on the light path in a second direction opposite to the first direction. The doubling chips are operable to receive the light and double the frequency of a portion of the received light. The microlens array is aligned with the VCSEL elements. A mount may be employed to mount the side stack of doubling chips by either side mounting or end mounting.
