Detuning regulation based on the scanning pump wavelength plays an important role in the generation of temporal solitons in an optical microcavity. Field evolution inside a CaF₂ microcavity during the detuning regulation process is demonstrated. It is found that a stable single soliton can be excited when modulation instability dominates in the microcavity during frequency tuning with an appropriate scanning speed and operational parameters. However, due to the excessive loss caused by tuning, the soliton eventually evolves into a DC distribution. The influence of different parameters on the light field after formation of the soliton is also studied. Other different parameters lead to different distributional forms of soliton evolution. For maintenance of the single soliton, the appropriate detuning parameter and pump power are changed suddenly after the soliton is generated, causing the soliton to remain stable. Moreover, in the single soliton region, a path within the parameter space of detuning and pump power is planned in order to compress the pulse width of the soliton, and the comb spectrum is broadened. The results of theoretical analysis are important for studying field and spectral characteristics during frequency detuning and for maintaining the temporal soliton in the microcavity.

基于扫描泵浦波长的失谐调节在光学微腔中时间孤子的产生中起着重要作用。CaF ₂内部的场演化演示了失谐调节过程中的微腔。发现在以适当的扫描速度和操作参数进行频率调谐期间，当调制不稳定性在微腔中占主导地位时，可以激发稳定的单孤子。然而，由于调谐造成的过度损耗，孤子最终演化为直流分布。还研究了不同参数对孤子形成后光场的影响。其他不同的参数导致孤子演化的不同分布形式。对于单个孤子的维护，在孤子产生后突然改变适当的失谐参数和泵浦功率，使孤子保持稳定。此外，在单孤子区，在失谐和泵浦功率的参数空间内规划了一条路径，以压缩孤子的脉冲宽度，并展宽梳状光谱。理论分析的结果对于研究频率失谐期间的场和光谱特性以及维持微腔中的时间孤子很重要。
