Abstract

一种波长锁定方法及激光器，用于无需使用热光系数为负数的高分子聚合物便能实现波长锁定功能。波长锁定方法包括：激光器获取与基准点对齐的目标波长作为输出波长(601)，基准点为波长锁定标准件的周期性频谱内唯一与目标波长对应的波谷点，周期性频谱为不受温度变化影响的频谱；激光器通过检测输出波长确定实际光功率差值(602)；激光器判断实际光功率差值是否等于最大光功率差值(603)，最大光功率差值为与目标波长对应的功率值；若不等于，则激光器根据实际光功率差值与最大光功率差值确定波长偏移量(604)，波长偏移量为受到温度变化影响的输出波长与目标波长之间的偏差值；激光器根据波长偏移量将输出波长修正至目标波长(605)。
