http://lapt.ece.northwestern.edu/files/2000-001.pdf Webbdiode laser is varied for optimal locking by means of a set of neutral density filters (NDF). The most stable locking was achieved with injection power range of 1.0–0.5 lW. The injection locked diode laser produces a single mode beam, which is 3 GHz shifted relative to the fundamental frequency of Ti–sapphire laser, with more than 100 mW ...

Webb10 apr. 2024 · The self-injection-locked diode laser can significantly reduce the linewidth down to a sub-100 kHz level but requires optical filtering that is much narrower than the laser cavity linewidth. Such optical filtering is usually sophisticated and beyond the capability of the normal dielectric coating approach. Here we develop a 0.16 nm … WebbInjection locking of a passively mode-locked laser. Abstract: We present and analyze a model of a passively mode-locked laser, which is subjected to injection of a coherent pulse train. The model, based on soliton perturbation theory, predicts the possibility of coherent injection locking, and gives analytical estimates for the locking ranges.
WebbAbstract: Injection locking has been actively researched for its possibility to improve laser performance for both digital and analog applications. When a modulated follower laser … WebbInjection locking of AlGaAs double-heterostructure (DH) lasers was studied with respect to locking bandwidth, required power, and coherence. The relation of the locking bandwidth versus the ratio of locked laser power to injected power was consistent with the classical analysis on injection locking phenomena reported by Adler [2]. The …
Injection locking and injection pulling are the frequency effects that can occur when a harmonic oscillator is disturbed by a second oscillator operating at a nearby frequency. When the coupling is strong enough and the frequencies near enough, the second oscillator can capture the first oscillator, causing it to have essentially identical frequency as the second. This is injection locking. When the second oscillator merely disturbs the first but does not capture it, the effect is called in…
