摘要	There is provided an end-pumped vertical external cavity surface emitting laser (VECSEL) in which a pump laser beam is incident on a laser chip at a right angle. In the external cavity surface emitting laser, a laser chip package is provided with a laser chip emitting light at a first wavelength by optical pumping, an external mirror is spaced apart from a top surface of the laser chip package to transmit a portion of the light emitted from the laser chip to the outside and to reflect the remainder to the laser chip, a heat sink is coupled to the bottom surface of the laser chip package to discharge heat generated by the laser chip, and a pump laser faces a bottom surface of the heat sink to emit pump light at a second wavelength perpendicular to the laser chip.
其他摘要	提供了一种端部泵浦垂直外腔表面发射激光器（VECSEL），其中泵浦激光束以直角入射在激光器芯片上。在外腔表面发射激光器中，激光芯片封装件设置有通过光泵浦发射第一波长的光的激光器芯片，外部镜子与激光器芯片封装的顶表面间隔开以透射一部分光从激光芯片发射到外部并将剩余部分反射到激光芯片，散热器耦合到激光芯片封装的底表面以释放由激光芯片产生的热量，并且泵浦激光器面向底部表面。散热器以垂直于激光芯片的第二波长发射泵浦光。
