An external-cavity diode laser is used to seed a pulsed Ti:sapphire laser from 839 to 860 nm. Because this wavelength range is off the gain peak of Ti:sapphire, a bandpass filter is used in the cavity to permit seeded operation. We describe a tunable, wide-field-of-view birefringent filter especially suited for use in seeded lasers. Measurements of the ratio of unseeded to seeded output as a function of seed power are also presented and demonstrate an approximately reciprocal dependence on the seed power.
一个外腔二极管激光器被用于从839至860纳米的波长范围内泵浦一个脉冲钛宝石激光器。由于这个波长范围偏离了钛宝石的增益峰值，因此在腔内使用了一个带通滤波器以实现泵浦操作。我们描述了一种特别适用于泵浦激光器的可调谐、宽视场双折射滤波器。文中还给出了无泵浦与有泵浦输出之比随泵浦功率变化的测量结果，结果表明该比值与泵浦功率大致呈倒数关系。
