XY系列液晶空间光调制器产品特点:

1、100%填充因子,90-95%高衍射效率

Meadowlark公司采用独特的硅板镀膜技术,在实现100%填充因子的基础上,有效的消除了SLM高阶衍射光的能量损失,使得空间光调制器的光能利用率提高到了90-95%。

2、高速寻址有效消除相位纹波

Meadowlark公司的液晶空间光调制器(LC SLM)采用模拟寻址方式,该方式的寻址速度可达6KHz,可以非常好的消除SLM的相位纹波(可做到0.1%以内)。而holoeye等公司提供的反射式空间光调制器寻址速度为60Hz,其产生的相位纹波大都在10%以上。

3、高损伤阈值

MLO的液晶SLM具有非常高的损伤阈值:10W/cm2 for CW Laser ;10MW/cm2 for Pulse Laser。我们的客户使用Average Power = 16 W, Rep Rate = 1 MHz, Pulse Width = 600 fs, beam diameter 5.5 mm的激光,通过检测一阶衍射衍射光的响应曲线,得到HSPDM512-1064相位型空间光调制器可承受的峰值功率密度为 110 MW/cm^2
