    • Methods of controlling semiconductor lasers are provided where the semiconductor laser generates a wavelength-modulated output beam λthat is directed towards the input face of a wavelength conversion device. The intensity of a wavelength-converted output λof the device is monitored as the output beam of the laser is modulated and as the position of the modulated output beam λon the input face of the wavelength conversion device is varied. A maximum value of the monitored intensity is correlated with optimum coordinates representing the position of the modulated output beam λon the input face of the wavelength conversion device. The optical package is operated in the data projection mode by directing an intensity-modulated laser beam from the semiconductor laser to the wavelength conversion device using the optimum positional coordinates. Additional embodiments are disclosed and claimed. Laser controllers and projections systems are also provided.
    • 提供了控制半导体激光器的方法,其中半导体激光器产生波长调制输出光束λ,其指向波长转换器件的输入面。 当激光器的输出光束被调制并且随着波长转换器件的输入面的调制输出光束λ的位置变化时,监视器件的波长转换输出λ的强度。 所监视的强度的最大值与表示波长转换装置的输入面的调制输出光束λ的位置的最佳坐标相关。 通过使用最佳位置坐标将来自半导体激光器的强度调制激光束引导到波长转换装置,以数据投影模式操作光学封装。 公开并要求保护附加实施例。 还提供激光控制器和投影系统。
