    • A laser source (10, 30, 40) comprising a laser medium (10) having a back facet (10B) and a front surface (10A), whereby the laser medium (10) is adapted to emit a laser beam through the front surface into an external cavity defined in length by a cavity end mirror (40) reflecting the laser beam back towards the laser medium (10). A wavelength tunable filter (30) is arranged between the laser medium (10) and the cavity end mirror (40) adapted for tuning the wavelength of the laser beam. The laser medium (10), the wavelength tunable filter (30), and the cavity end mirror (40) are arranged in a spatially linear cavity structure substantially in a line without angular redirection of the laser beam in the cavity between the laser medium (10) and the cavity end mirror (40).
    • 一种包括具有背面(10B)和前表面(10A)的激光介质(10)的激光源(10,30,40),由此所述激光介质(10)适于通过所述前表面 通过将激光束反射回激光介质(10)的空腔端镜(40)进入长度限定的外部空腔。 波长可调滤波器(30)布置在激光介质(10)和适于调谐激光束波长的空腔端镜(40)之间。 激光介质(10),波长可调滤波器(30)和空腔端镜(40)被布置在基本上以线的空间线性空腔结构中,而不在激光介质之间的空腔中的角度重定向 10)和腔端镜(40)。
