An injection-locked pulsed Ti:sapphire laser oscillating at dual wavelengths is demonstrated for the first time to our knowledge. By use of two feedback loops, seeds of two independent master lasers are locked on specific longitudinal modes of a power oscillator, leading to a stable dual-wavelength oscillation over a long time scale. The two injection-locked pulsed outputs completely overlap in time, with spectral purities reaching a Fourier-transform limit. The dual-wavelength oscillation is controlled by the master lasers only, allowing for flexible selectivity of the two wavelengths and full controllability of the relative two-wavelength pulsed energies.
据我们所知，首次展示了一种在双波长下振荡的注入锁定脉冲钛宝石激光器。通过使用两个反馈回路，两个独立主激光器的种子被锁定在功率振荡器的特定纵向模式上，从而在长时间尺度上实现稳定的双波长振荡。两个注入锁定脉冲输出在时间上完全重叠，光谱纯度达到傅里叶变换极限。双波长振荡仅由主激光器控制，从而实现两个波长的灵活选择性以及相对双波长脉冲能量的完全可控性。
