A hybrid amplifier chain composed of Ti:chrysoberyl and Ti:sapphire is proposed to control spectral gain narrowing in this letter. The Ti:chrysoberyl crystal is employed as the host material of the frontier amplification stage with the polarization parallel to a axis. According to the numerical simulation, the seeding pulse with a proper wavelength center is required to generate a broader spectrum, and spectra broader than 120 nm are available with total net gain from 104 to 1010. The simulation proves that the amplified spectrum can even support pulse shorter than the seed pulse.
Research Highlights► We modeled a hybrid amplifier chain based on Ti:chrysoberyl and Ti:sapphire. ► The emission spectrum of Ti:chrysoberyl gets two peaks with E//a. ► The synthetic spectrum could counter the gain narrowing effectively.
