Whisper Fiber-Output Single-Wavelength Laser
The Whisper fiber laser is a diode-based CW solid-state source with ultralow noise and compact packaging, offering higher efficiency than DPSS/gas lasers and high cost effectiveness. PIC's WhisperIT® eliminates mode hopping and minimizes noise. Integrated drivers and patented technology provide high stability, low coherence and low speckle across time and temperature. FC/APC output or custom application-matched collimator output is available. Technical support: PIC Weilin Optoelectronics works closely with customers on requirements and advanced solutions throughout product life. Zero downtime: stocked standard-product materials ensure timely volume-OEM delivery and avoid production interruption. Integrated solutions: full support from early development to mass production, with early design verification and validation for long-term reliability and stability.
