| Effect of intense chirped pulses on the coherent phonon generation in Te (2007) | |||||||||||||
Abstract | |||||||||||||
| The authors have studied the influence of chirped laser pulses on the coherent phonon generation in single crystal Te. They have shown that the pulse chirp affects the amplitude of coherent phonons with A1 symmetry in the case of intense excitation only. By varying the chirp of an intense exciting pulse, the authors demonstrated that negatively chirped pulses are almost twice more effective in the creation of lattice coherence than positively chirped pulses. | |||||||||||||
