美国加州Laser Power公司生产的深蓝色微型激光器由激活增益介质、非线性频率耦合晶体和泵浦二极光源(809nm)组成。增益介质是一个掺稀土元素微激光晶体,当用二极管发出的激光激励增益介质时,发射波长为900nm偏振光。非线性倍频晶体与900nm波长光相位匹配。非线性倍频晶体和掺稀土晶体连接在一起形成一个组合腔。二极管发射的泵浦光泵浦组合腔,在腔中产 The dark blue miniature laser produced by Laser Power of California, USA consists of an active gain medium, a nonlinear frequency coupled crystal and a pump diode light source (809nm). The gain medium is a rare earth-doped micro-laser crystal emitting 900nm polarized light when excited by a laser emitting diode. Nonlinear frequency doubling crystal phase matching with 900nm wavelength light. Non-linear frequency doubling crystals and rare earth-doped crystals together to form a combined cavity. The diode-pumped pump light pumped the combined chamber, which is produced in the chamber
