Tailoring the pulse characteristics of LiB3O5-based femtosecond optical parametric oscillators by temperature tuning

|
By Songyin Yu, Zhaowei Zhang, Zhenyu Yang, Mengke Qin
| Optica Verified
We show that the phase mismatch in LiB3O5 (LBO) crystals is approximately proportional to the temperature deviation from the phase-matching temperature of crystals. Moreover, a fixed temperature deviation would result in approximately the same amount of phase mismatch over a large range of wavelengths. Based on this, we demonstrate that the pulse characteristics of LBO-based femtosecond optical parametric oscillators (OPOs) can be tailored by simply tuning the crystal temperature.
