The method of output laser.
Background technology
Existing high-power ultrashort pulse laser complex structure, beam quality with step by step amplify gradually degrade, this be because
For, existing mode locking oscillator is all small-sized steady cavity oscillations device, due to this agitator output it is not high, so need increase
Plus one or more levels amplifier is exported with the pulse for obtaining more power, in this process, due to originals such as thermal distoftion, differences
Cause, beam quality are gradually degraded, and as state-of-the art is limited, the core component SESAM of mode-locked laser is generally costly,
And small volume (the SESAM prices of a piece of 3mmx3mm sizes are at 3000 Euros or so), so using present institute's mode oscillation device more
Steady cavity oscillations device, so only needs to the SESAM of 2x2mm as Effect of Back-Cavity Mirror, and the saturation flux of SESAM is typically about 100uJ/
Cm2, as steady chamber is designed, frequently as Effect of Back-Cavity Mirror, spot size diameter is about 500um to SESAM, and SESAM is usually operated at 5 times and satisfies
With the interval of flux, then, a steady chamber mode locking oscillator intracavity pulse energy is about 0.19uJ, and outgoing mirror is if 2%
