Master oscillator power amplifier laser system and method

An integrated master oscillator power amplifier (MOPA) laser module and a method of manufacturing the same. The MOPA includes: a prefabricated chassis including a plurality of surfaces; a master oscillator laser (MO) permanently attached to at least one first surface of the plurality of surfaces; a power amplifier (PA) permanently attached to at least one second surface of the plurality of surfaces, where a spatial relationship between the at least one first surface and the at least one second surface determines an alignment between the MO and the PA; and a beam transport system (BTS) permanently attached to the prefabricated chassis and including a plurality of optical elements for transmitting light output from the MO to the PA for amplification. 整合的主振荡器功率放大器(MOPA)激光器模块及其制造方法。MOPA包括：预制底盘，包括多个表面；主振荡器激光器(MO)，所述MO持久地附着到所述多个表面中的至少一个第一表面；功率放大器(PA)，所述PA持久地附着到所述多个表面中的至少一个第二表面，其中，所述至少一个第一表面与所述至少一个第二表面之间的空间关系确定所述MO与所述PA之间的对准；以及光束传输系统(BTS)，所述BTS持久地附着到所述预制底盘，且包括用于将从所述MO输出的光传输到所述PA进行放大的多个光学元件。
