脉冲产生方法和激光光源设备
摘要：
本发明涉及脉冲产生方法和激光光源设备。本发明使得可以同时设置或自动设置光脉冲的脉冲峰值和脉冲宽度。在一种构造中，包括了：输出激光的发光元件；将驱动电流供给发光元件的驱动电流源部分；将用于激光脉冲调制的调制电压施加到发光元件的调制器；以及调制控制部分，控制调制图形以作为调制器的调制电压的脉冲调制的图形，其中所述调制控制部分根据关于驱动电流值的信息来设置调制图形中的调制电压值，并将关于调制图形的信息发送到调制器以使得调制电压达到设置值。
摘要（英）：

The invention relates to a pulse generating method and a laser light source device. The pulse peak and pulse width of light pulses can be set simultaneously or automatically. In one structure, the laser light source device comprises a light-emitting component, a drive current source part, a modulator and a modulation control part, the light-emitting component is used for outputting laser; the drive current source part is used for supplying drive current to the light-emitting component; the modulator is used for applying modulation voltage for laser pulse modulation on the light-emitting component; and the modulation control part is used for controlling a modulation pattern into a pattern for pulse modulation of the modulation voltage of the modulator, setting the modulation voltage value in the modulation pattern according to information on the value of the drive current and sending information on the modulation pattern to the modulator so that the modulation voltage reaches the set value.
