滨松光子学 K.K 公司的一种采用特殊非线性光学晶体的可调波长激光器新近研制成功,它可从可见光到近红外波长连续变化。该公司将提供这样的可调波长激光器。它具有宽带振荡、有效作用距离复盖各个波长区及抗激光损伤的特点,因此,其耐用性得以增强。该器件应用光学参量振荡原理。当激光束以激励形式辐射到晶体时,它便分散为二个不
Hamamatsu Photonics K.K., a tunable wavelength laser with a special nonlinear optical crystal, was recently developed to continuously vary from visible to near infrared wavelengths. The company will provide such a tunable wavelength laser. It has wideband oscillation, effective range of coverage of each wavelength and anti-laser damage characteristics, therefore, its durability is enhanced. The device uses optical parametric oscillation principle. When the laser beam radiates to the crystal in an excited form, it disperses into two
