Laser diode acoustic noise reduction |
摘要 |
A laser diode assembly and associated heat sink and excitation leads constructed to avoid the electromagnetic or magnetostrictive generation of stress or elastic wave disturbances in the diode, heat sink or associated components so as to maintain spectral purity in the diode laser emission. An improved laser diode assembly avoids the generation of elastic waves or vibrations within the leads, heat sink or associated structure of a laser diode by running excitation leads in a magnetic field cancellation arrangement to prevent magnetostrictively induced elastic waves in structure connected to the laser diode and to avoid vibration induced by coupling between the lead currents and external magnetic fields. The heat sink, electrical input and return leads and associated structure may be fabricated of a nonmagnetostrictive material to avoid magnetostrictively induced acoustic disturbances created by other magnetic field sources in the use environment of the laser diodes.
