A compact passively Q-switched Yb:YAG microchip laser is demonstrated. Featuring a semiconductor saturable-absorber mirror (SESAM), the laser yields pulses of 219 ps when the length of the microchip Yb:YAG crystal is 100 μm and the beam quality is M2

椭圆偏振光谱因其独特的优点广泛应用于薄膜科学和技术中。光度法椭圆偏振光谱中椭圆旋向是不能直接确定的,从而不能确定椭偏参数Δ。这一定程度上有碍椭圆偏振光谱的应用。本文引入克拉末-克朗尼格(Kramers-Kronig)关系,推导出椭偏参数的Ψ-Δ关系,从频谱的信息得出椭圆旋向。并比较了其应用的结果,表明由此可实现实验数据从[tanΨ(ω),cosΔ(ω)]谱到[Ψ(ω),Δ(ω)]谱的转换。
The visibility in magnetostrictive fiber-optic interferometric sensors using a Gaussian laser beam is analyzed. It is shown that the conventional Gaussian laser beam has little influence on the visibility. The visibility depends strongly on the input stat
A filter-less frequency doubling generator with tunable phase shift based on dual-polarization modulation is proposed and analyzed. The setup is composed with a continuous-wave laser, a dual-polarization Mach-Zehnder modulator and a linear polarizer follo
