Sequential-Pulse Single-Frequency Laser Power Amplification Apparatus And Sequence Controllable Multi-Laser System

A sequential-pulse single-frequency laser power amplification apparatus applied for an atomic system, comprising a sequence control unit and a power amplification unit, wherein

• the sequence control unit is configured to modulate parameters of an incident source laser and control a sequence switch for the source laser, for generating a primary laser;
• and
• the power amplification unit is configured to power amplify the primary laser, to generate a secondary laser;
• wherein
• when the primary laser is incident into the power amplification unit, the secondary laser resonates with the atomic system;
• when the power amplification does not have the primary laser injected, the secondary laser is detuned from the atomic system.
