Single Longitudinal Mode

Lasers | Photonics Handbook®

Lasers | Photonics Handbook®

A laser that produces multiple longitudinal modes has a limited coherence - different wavelengths cannot stay in phase over extended distances. Applications
such as holography, which demand excellent coherence, benefit from using a single-longitudinal-mode laser. For some laser types with a…

Genesis CX-SLM

Genesis CX-SLM

--> Genesis CX SLM-Series The Genesis CX SLM-Series is a single longitudinal mode, TEM 00 is intended for single frequency, interferometric applications, and is available at 355, 460, 480, 488, 514, 532, and 577 nm with up to 4W of output power. The TEM 00 beam parameters remain constant from…

…polarization-sensitive output coupling enable unidirectional lasing that is the foundation for a single frequency operation. The small size of the resonator enables a wide separation of the longitudinal modes and simple thermal frequency tuning (over 30 GHz). The application of mechanical force via…

…in single longitudinal mode.
Within the temperature locking range, the elliptical beam profile has a dark spot
approximately centered in the ellipse (see figure 2). The presence of a dark spot indicates
that the laser in locked by the VHG and operating single mode longitudinal mode.

…stable operation on a
single longitudinal mode. The NPRO naturally favors this single-mode operation
because its short cavity length results in
large frequency spacing between the longitudinal modes, relative to the gain bandwidth of the Nd:YAG crystal. The mode
nearest the peak…
