| Abstract: | Dual wavelength lasers are discussed, covering fundamental aspects on the spectroscopy and laser dynamics of these systems.
Results on Tm:Ho:Er:YAG dual wavelength laser action (Ho at 2.1 μm and Er at 2.9 μm) as well as Nd:YAG (1.06 and 1.3 μm) are
presented as examples of such dual wavelength systems. Dual wavelength lasers are not common, but there are criteria that
govern their behavior. Based on experimental studies demonstrating simultaneous dual wavelength lasing, some general conclusions
regarding the successful operation of multi-wavelength lasers can be made. |
