报道了Er：Yb：磷酸盐玻璃激光器的双波长可调谐运转。激光本征态的空间分离和使用两个适当设计的腔内标准具允许将两个波长从1540.5独立调谐到1562.7 nm。用迈克尔逊干涉仪监测所产生的拍音，实验表明它在2.7THz范围内是可调的，线宽小于10kHz。几个应用程序进行了讨论。
Dual tunable wavelength operation of a Er:Yb:phosphate glass laser is reported. The spatial separation of the laser eigenstates and the use of two properly designed intracavity etalons permit one to tune the two wavelengths independently from 1540.5 to 1562.7 nm. The generated beat note, monitored using a Michelson interferometer, is experimentally shown to be adjustable from de to 2.7 THz, The linewidth of this beat note is found to be less than 10 kHz. Several applications are discussed.
