具体实施方式
为了便于理解本申请，下面将参照相关附图对本申请进行更全面的描述。附图中给出了本申请的较佳实施例。但是本申请可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反的，提供这些实施例的目的是使对本申请的公开内容的理解更加透彻全面。
除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本申请。本申请的权利要求书、说明书以及说明书附图中的术语“第一”、“第二”等是用于区别不同对象，而不是用于描述特定顺序。
本申请的一实施例公开一种激光器的控制方法，应用于光纤激光器，但本申请公开的激光器的控制方法并不仅限于应用在光纤激光器上。下面将结合附图对本实施例中的技术方案进行说明，具体实施方式中涉及到的激光器的控制方法只是较佳的实施例，并非本申请所有可能的实施例。
参考图1和图2，其中图1为本申请的一实施例中激光器的控制方法的示意图，图2为本申请的一实施例中控制信号、捕捉信号以及激光脉冲的示意图。
所述激光器的控制方法包括：
步骤1：采集控制信号的上升沿或者下降沿以形成捕捉信号。
步骤2：根据所述捕捉信号输出激光脉冲。
步骤3：在输出一个激光脉冲时开始计时。
步骤4：在计时获得的时间达到激光脉冲的最小周期时允许输出下一个激光脉冲，在计时获得的时间超过激光脉冲的最大周期时停止输出下一个激光脉冲。
在一种可能的实施方式中，输出激光脉冲的时间点跟随捕捉信号上捕捉到上升沿或者下降沿的时间点。
通过在输出一个激光脉冲时开始计时，并且只有在计时获得的时间达到激光脉冲的最小周期时才允许输出下一个激光脉冲，因此激光脉冲的周期不会小于最小周期，也即激光脉冲的频率不会超过设定的最高频率。在计时获得的时间超过激光脉冲的最大周期时停止输出下一个激光脉冲，因此激光脉冲的周期不会超过最大周期，也即激光脉冲的频率不会小于设定的最低频率。控制信号的周期具有不确定性，通过本实施例中所述激光器的控制方法一方面能够跟随控制信号输出激光脉冲，另一方面则能够将激光脉冲的周期限制在最小周期与最大周期之间，有利于保障激光器的工作性能，减少安全隐患。
在本申请的实施例中，通过最小周期计时信号和最小周期限制信号来限制激光脉冲的最小周期。在步骤3计时的同时形成最小周期计时信号，所述最小周期计时信号在计时停止时的相位与计时开始时的相位相反。例如，以高电平表示从计时开始持续到计时停止，并且所述高电平持续的时长为设定的激光脉冲的最小周期，在计时停止后由高电平转化为低电平。在步骤3计时的同时还形成与所述最小周期计时信号反相的最小周期限制信号，开始计时后当所述最小周期限制信号的相位变化时允许输出下一个激光脉冲。例如，在最小周期计时信号为高电平时最小周期限制信号为低电平，在最小周期计时信号为低电平时最小周期限制信号则为高电平，当最小周期限制信号为高电平允许输出下一个激光脉冲。在输出下一个激光脉冲时将重新开始计时，也即从输出上一个激光脉冲开始的计时将清零，从输出下一个激光脉冲时开始再次计时。
参考图3和图4，其中图3为本申请的一实施例中控制信号a、捕捉信号a、 最小周期计时信号以及最小周期限制信号的示意图，图4为本申请的一实施例中控制信号b、捕捉信号b、最小周期计时信号以及最小周期限制信号的示意图。
如图3中所示意的，在捕捉信号a上的时间点t1和t2捕捉到了控制信号a上相邻的两个上升沿，并且时间点t1和t2之间的间隔时间大于最小周期计时信号表示的最小周期Tmin。由步骤4可知，在计时获得的时间达到激光脉冲的最小周期时允许输出下一个激光脉冲。图3中时间点t1和t2之间的间隔时间大于最小周期Tmin，在捕捉信号a上的时间点t2，最小周期限制信号由低电平转换为高低平，采集到控制信号a的上升沿时将输出下一个激光脉冲。
如图4中所示意的，在捕捉信号b上的时间点t1、t2以及t3捕捉到了控制信号b上的三个上升沿，并且时间点t1和t2之间的间隔时间小于最小周期Tmin。由步骤4可知，在计时获得的时间达到激光脉冲的最小周期时允许输出下一个激光脉冲，因此在计时获得的时间小于激光脉冲的最小周期时将不能输出下一个激光脉冲。图4中时间点t1和t2之间的间隔时间小于最小周期Tmin，在捕捉信号b上的时间点t2，最小周期限制信号仍然为低电平，因此采集到捕捉信号b的上升沿时将不能输出下一个激光脉冲。图4中时间点t1和t3之间的间隔时间大于最小周期Tmin，在捕捉信号b上的时间点t3，最小周期限制信号为高电平，因此在时间点t3采集到捕捉信号b的上升沿时可以输出下一个激光脉冲。
在本申请的实施例中，通过最大周期计时信号和最大周期限制信号来限制激光脉冲的最大周期。在步骤3计时的同时形成最大周期计时信号，所述最大周期计时信号在计时停止时的相位与计时开始时的相位相反。例如，以高电平表示从计时开始持续到计时停止，并且所述高电平持续的时长为设定的激光脉冲的最大周期，在计时停止后由高电平转化为低电平。在步骤3计时的同时还形成与所述最大周期计时信号反相的最大周期限制信号，开始计时后当所述最大周期限制信号的相位变化时停止输出下一个激光脉冲。例如，在最大周期计时信号为高电平时最大周期限制信号为低电平，在最大周期计时信号为低电平 时最大周期限制信号则为高电平，当最大周期限制信号为高电平时停止输出下一个激光脉冲。在一种可能的实施方式中，因最大周期限制信号为高电平而停止输出下一个激光脉冲后，如果激光器接收到新的控制信号，将重新执行步骤1至步骤4，此时将重新开始计时，也即从输出上一个激光脉冲开始的计时将清零，从输出下一个激光脉冲时开始再次计时。
参考图5和图6，其中图5为本申请的一实施例中控制信号c、捕捉信号c、最大周期计时信号以及最大周期限制信号的示意图，图6为本申请的一实施例中控制信号d、捕捉信号d、最大周期计时信号以及最大周期限制信号的示意图。
如图5中所示意的，在捕捉信号c上的时间点t1和t2捕捉到了控制信号c上相邻的两个上升沿，并且时间点t1和t2之间的间隔时间小于最大周期计时信号表示的最大周期Tmax。由步骤4可知，在计时获得的时间超过激光脉冲的最大周期时停止输出下一个激光脉冲，因此在计时获得的时间没有超过激光脉冲的最大周期时输出下一个激光脉冲。图5中时间点t1和t2之间的间隔时间小于最大周期Tmax，因此在捕捉信号c上的时间点t2，最小周期限制信号仍然为高电平，而最大周期限制信号则仍然为低电平，采集到捕捉信号b的上升沿时将输出下一个激光脉冲。
如图6中所示意的，在捕捉信号d上的时间点t1和t2捕捉到了控制信号d上相邻的两个上升沿，并且时间点t1和t2之间的间隔时间大于最大周期计时信号表示的最大周期Tmax。由步骤4可知，在计时获得的时间超过激光脉冲的最大周期时停止输出下一个激光脉冲。图6中时间点t1和t2之间的间隔时间大于最大周期Tmax，因此在捕捉信号d上的时间点t2，最小周期限制信号转化为低电平，而最大周期限制信号则转化为高电平，采集到捕捉信号b的上升沿时将停止输出下一个激光脉冲。
在一种可能的实施方式中，在输出一个激光脉冲时开始对泵浦源的工作时间计时，在所述工作时间达到最大工作时间时激光器关闭泵浦源。
参考图7，为本申请的一实施例中控制信号e、捕捉信号e以及最大工作时 间的示意图。在捕捉信号e上的时间点t1和t2捕捉到了控制信号e上相邻的两个上升沿，并且在输出一个激光脉冲时开始对泵浦源的工作时间计时，如果工作时间超过最大工作时间θ，则激光器将关闭泵浦源。具体而言，激光器可以通过关闭泵浦源的工作电流，使得泵浦源停止工作。
本申请的一实施例公开一种激光器的电子控制装置。参考图8，为本申请的一实施例中激光器的电子控制装置300的示意图。该激光器的电子控制装置300包括：微控制单元(MCU)301、现场可编辑逻辑门阵列(FPGA)302、一个或者多个数模转换器303以及控制接口304。所述微控制单元301与所述现场可编辑逻辑门阵列302相互进行通信。所述现场可编辑逻辑门阵列302通过所述一个或者多个数模转换器303进行数模转换，通过所述控制接口304与应用设备控制板卡400以及上位机500进行通信。所述现场可编辑逻辑门阵列302可以通过所述一个或者多个数模转换器303输出控制信号以控制泵浦源的工作电流。所述现场可编辑逻辑门阵列302还可以向激光器的声光控制板卡发送控制指令。所述控制接口304可以是DB25控制接口。所述应用设备控制板卡400装设在激光打标设备等其他应用激光器的设备。
