We show that utmost possible Raman coherence between equally populated levels can be excited by two-photon resonant bichromatic field far from one photon resonance by means of relaxation processes. On this basis we suggest a mechanism for generation of extremely short pulses with high pulse duty factor and large energy in the pulse. It can be realized in solid materials, such as the rare-earth doped dielectrics with long-lived spin coherence or nitrogen-vacancy [Formula Presented] centers in diamond and provide a simple, reliable, and convenient technique for many practical applications. 2003 The American Physical Society.
