WebJul 10, 2024 · A prism compressor is an optical device used to shorten the duration of a positively chirped ultrashort laser pulse by giving different wavelength components a different time delay. It typically consists of two prisms and a mirror. Figure 1 shows the construction of such a compressor. In Ti-sapphire lasers employing Kerr-lens modelocking, chirped mirrors are often used as the sole means to compensate group delay variations. Considering the above numbers a single mirror can compensate 4 μm optical path length. Considering the group velocity this is enough for the 3 m air inside the cavity, for the 3 mm of Ti:sapphire crystal three more mirrors are needed, so that a simple Z-cavity can already be compensated. On the other hand, the gain of the crystal of abou…
