在相似的实验条件下，分析了用近红外随机激光源和窄带激光器通过反射和透射获得的不同图案的单次拍摄红外图像。Nd基晶体粉末随机激光器提供了无散斑透射和反射红外图像，其对比度噪声比高于窄带激光器。这些结果开辟了新的可能性，以提高光电和生物医学应用领域的高分辨率成像。
Single shot infrared images of different patterns obtained, both by reflection and transmission, with a near infrared random laser source and a narrowband laser are analyzed under similar experimental conditions. The Nd-based crystal powder random laser provides speckle-free transmission and reflection infrared images with higher values of contrast to noise ratio than those obtained with the narrowband laser. These results open up new possibilities to enhance the field of high resolution imaging for optoelectronic and biomedical applications.
