Whisper Free-Space Single-Wavelength Laser
The Whisper laser is a laser-diode-based continuous-wave solid-state laser offering ultralow noise. Its compact package significantly reduces footprint, with higher operating efficiency than DPSS and gas lasers and excellent cost effectiveness. PIC's proprietary WhisperIT® technology eliminates mode hopping and reduces optical noise to an extremely low level. Integrated driver circuitry and patented technology provide high stability, low coherence and low speckle, ensuring excellent performance over time and temperature changes. Whisper lasers are available with a collimated circular beam or a customized beam size matched to the application.
