Description

一种同时具备连续和脉冲输出的铥激光医用固体激光器
技术领域
本发明属于激光治疗装置技术领域，具体涉及一种同时具备连续和脉冲输出的铥激光医用固体激光器。
背景技术
CN207545202U-同时具备体内碎石和软组织切除的铥激光医疗装置，该医疗装置虽然可以做体内碎石手术或软组织切除手术。由于脉冲峰值越高且脉冲能量大碎石效率更高，本发明采用混频调制脉冲模式，更进一步提高了单脉冲峰值功率同时又加大了脉冲序列的能量，将有效提高碎石效率。另外本发明还可以提供更高功率的连续铥激光，提高临床上对前列腺增生、膀胱肿瘤等软组织的气化切除效率，进一步缩短手术时间。
发明内容
本发明提供一种同时具备连续和脉冲输出的铥激光固体医用激光器，具备了同时对前列腺等软组织气化切除、体内碎石两种手术模式。
一种同时具备连续和脉冲输出的铥激光医用固体激光器，包括激光谐振腔、聚焦镜和光学耦合器；所述激光谐振腔包括高反镜、掺铥离子激光晶体、半导体泵浦激光器和输出镜。
进一步的，所述半导体泵浦激光器包括两个平行巴条排组，一排为连续输出巴条排组，一排为脉冲输出巴条排组；所述连续输出巴条排组和所述脉冲输出巴条排组的间距小于2mm，且所述连续输出巴条排组和所述脉冲输出巴条排组分别连接不同电源。
进一步的，所述连续输出巴条排组连接直流电源，所述脉冲输出巴条排组连接脉冲电源；当向所述连续输出巴条排组供给直流电源时，所述激光谐振腔产生连续铥激光；当向所述脉冲输出巴条排组供给脉冲电源时，所述激光谐振腔产生脉冲铥激光。
进一步的，所述半导体泵浦激光器设有三组或五组，所述半导体泵浦激光器沿所述掺铥离子激光晶体外周均匀设置。
进一步的，所述掺铥离子激光晶体为Tm：YAG晶体或Tm：YAP晶体。

进一步的，所述脉冲铥激光为混频调制模式脉冲序列激光。
与现有技术相比，本发明提出的固体激光器，其半导体泵浦激光器有三个特征：其一：包括两个并排平行巴条排组，一排为连续输出巴条排组，一排为脉冲输出巴条排组。其二：连续输出巴条排组和脉冲输出巴条排组的间距小于2mm，间距越小越利于对掺铥激光晶体的泵浦和激光器的泵浦效率。其三：连续输出巴条排组和脉冲输出巴条排组可以分别连接不同的独立电源，连续输出巴条排组连接直流电源，脉冲输出巴条排组连接脉冲电源。也即是：当向连续输出巴条排组施以直流电源时，激光器产生连续铥激光。当向脉冲输出巴条排组施以脉冲电源时，激光器产生脉冲铥激光。
传统铥激光是连续激光输出，其常见功率在100W级，临床多用于前列腺增生膀胱肿瘤等软组织的气化切除，不具备碎石功能。本发明中的脉冲铥激光的波形为混频调制式脉冲序列，每个脉冲序列由若干个子脉冲构成，每个子脉冲的宽度、幅度、间隔都可以编程。既保证了子脉冲激光的高峰值功率，又可实现脉冲序列的大能量，可以有效提高碎石效力。

具体实施方案：
下面结合附图和具体实施例对本发明进行详细说明。
本实施例提出一种同时具备连续和脉冲输出的铥激光医用固体激光器，如图1所示，包括激光谐振腔50、聚焦镜60和光学耦合器70；其中，激光谐振腔50包括高反镜10、掺铥离子激光晶体30、半导体泵浦激光器40和输出镜20，聚焦镜60和耦合器70依次设置在激光谐振腔50靠近输出镜20的一端，且聚焦镜60靠近输出镜20一侧设置。
如图2所示，半导体泵浦激光器40沿掺铥离子激光晶体30外周均匀设置，产生的铥激光依次经聚焦镜60和耦合器70处理后输出。其中，掺铥离子激光晶体30为Tm：YAG晶体或Tm：YAP晶体。半导体泵浦激光器40的波长为785nm或793nm，分别与Tm：YAG晶体或Tm：YAP晶体相匹配。半导体泵浦激光器40为奇数组，常设有三组或五组，在本实施例中，选择三组半导体泵浦激光器40。
如图3所示，半导体泵浦激光器40包括两个平行巴条排组，一排为连续输出巴条排组41，一排为脉冲输出巴条排组42。连续输出巴条排组41和脉冲输出巴条排组42的间距d小于2mm，间距d越小越利于对掺铥激光晶体30的泵浦和激光器的泵浦效率。且连续输出巴条排组41和脉冲输出巴条排组42分别连接不同电源。
也即是连续输出巴条排组41连接直流电源，脉冲输出巴条排组42连接脉冲电源。当向连续输出巴条排组41供给直流电源时，激光谐振腔50产生连续铥激光；当向脉冲输出巴条排组42供给脉冲电源时，激光谐振腔50产生脉冲铥激光。
如图4所示，另一种固体激光器的结构示意图，在谐振腔50中包括两组半导体泵浦激光器40和与其相适配的掺铥激光晶体30，两组半导体泵浦激光器40和掺铥激光晶体30形成串联结构。
进一步的，传统铥激光是连续激光输出，其常见功率在100W级，临床多用于前列腺增生膀胱肿瘤等软组织的气化切除，不具备碎石功能。如图5所示，本实施例中的脉冲铥激光的波形为混频调制式脉冲序列，每个脉冲序列由若干个子脉冲构成，每个子脉冲的宽度、幅度、间隔都可以编程。既保证了子脉冲激光的高峰值功率，又可实现脉冲序列的大能量，可以有效提高碎石效力。
在本实施例中，掺铥离子激光晶体30为Tm：YAG晶体，相应地，半导体泵浦激光器40的波长为785nm，需要产生连续铥激光时，向半导体泵浦激光器40中的连续输出巴条排组41供给直流电源，即对连续输出巴条排组41施以0-50A恒流的直流电源，激光谐振腔50产生连续铥激光，这种连续铥激光适用于前列腺等软组织切割气化。本实施例中半导体泵浦激光器40的连续输出巴条排组41由六个巴条组成，每个巴条的最大功率50W；激光谐振腔50可输出100W级连续铥激光，对前列腺等软组织具有更好的切割气化和凝血效果。
需要产生脉冲铥激光时，向半导体泵浦激光器40中的脉冲输出巴条排组42供给脉冲电源，即对脉冲输出巴条排组42施以脉冲电源，提供高速脉冲电流，激光谐振腔50产生脉冲铥激光，这种脉冲铥激光适用于体内碎石。在本实施例中半导体泵浦激光器40的脉冲输出巴条排组42由六个巴条组成，每个巴条的最大峰值功率250W。
当脉冲铥激光采用均匀脉冲模式时，脉冲电源具有超高峰值电流，脉冲宽度2ms，脉冲激光峰值功率250W，单脉冲能量0.5J。
当脉冲铥激光采用本实施例中所述的混频调制式脉冲序列模式时，脉冲序列含有40个子脉冲，脉冲序列宽度为4ms，子脉冲的脉冲宽度0.05ms，每个脉冲输出巴条排组42的单个巴条的最大峰值功率可提高到500W，单个子脉冲激光峰值功率可提高到500W，脉冲序列的脉冲能量1.0J。即实现了脉冲铥激光的高峰值功率，又保证了脉冲序列的高能量，可大大提高碎石效率，性能优于均匀脉冲铥激光。
在本实施例中，采用均匀脉冲模式的脉冲铥激光，能产生10-2000Hz的脉冲铥激光，激光峰值功率一般可达到平均功率的5倍。采用混频调制式脉冲模式的脉冲铥激光，激光峰值功率可提高到平均功率的10倍且脉冲序列的能量更大，碎石效果较均匀脉冲模式更好。
1、本发明为多功能铥激光器治疗装置及激光治疗方法，不仅具备碎石功能还可以实现软组织的气化切除功能，实现一机多用，节约了设备购置成本。本装置结构简单，安全控制，适普性广且使用方便。
2、本发明提出的固体激光器，其半导体泵浦激光器有三个特征：其一：包括两个并排平行巴条排组，一排为连续输出巴条排组，一排为脉冲输出巴条排组。其二：连续输出巴条排组和脉冲输出巴条排组的间距小于2mm，间距越小越利于对掺铥激光晶体的泵浦和激光器的泵浦效率。其三：连续输出巴条排组和脉冲输出巴条排组可以分别连接不同的独立电源，连续输出巴条排组连接直流电源，脉冲输出巴条排组连接脉冲电源。也即是：当向连续输出巴条排组施以直流电源时，激光器产生连续铥激光。当向脉冲输出巴条排组施以脉冲电源时，激光器产生脉冲铥激光。
以上对本发明的实施例进行了详细说明，所述内容仅为本发明的较佳实施例，不能被认为用于限定本发明的实施范围。凡依本发明申请范围所作的均等变化与改进等，均应仍归属于本发明的专利涵盖范围之内。
