该处意在表明:作为电磁射线的一种,伽马射线与光波和无线电波类似,但是只是在……上略短。通过常理可判断应该是在波长上。故应选择wavelength。pace意为“步调,步法”,与射线无关;frequency意为“频率”,频率不论长短.而论快慢;rate意为“比率,等级”.亦不能用short来形容,可说small rate。

We demonstrate the operation of a CW multi-wavelength erbium-doped fiber laser covering the whole C-band. The laser system consists of a frequency-shifted ring cavity with a new type of periodic filter, namely a fiber Bragg grating array. Careful control of the individual grating strength has ...

For instance, red light has a lower frequency and longer wavelength compared to blue light. This is why we see red objects as having a longer wavelength and blue objects as having a shorter wavelength. 中文回答: 频率和波长是波的研究中的两个基本概念。频率指的是波在单位时间内完成的周期或振动...
Phase-matching of light waves is a critical condition for maximizing the efficiency of nonlinear frequency conversion processes in nonlinear optical crystals; however, phase-matching, commonly achieved by tuning birefringence, is often difficult to achieve over a wide wavelength range. Here, full-wavelen...
