Abstract
The development and characterization of a room-temperature single-mode 2-micron TmHo:KYF laser are presented A maximum single-mode CW output power of 70 mW at the central wavelength of 2.078 micron has been obtained. In multimode operation, KYF laser has showed, to our knowledge, the largest tunability range (99 nm) ever obtained for Tm-Ho codoping in any crystalline host, whereas the single-mode emission could be tuned over a range of 40nm. Frequency and relative intensity noise have been investigated showing a 1 -ms emission linewidth of 600 kHz and an intensity noise spectrum which is quantum-noise limited for Fourier frequencies higher than 1 MHz.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
