Abstract
Mid-infrared Er:YAG (2.94 μm) and Er,Cr:YSGG (2.78 μm) lasers are effectively utilized for dental hard tissue treatment due to their high absorption into water and/or hydroxide ion, respectively [1-6]. We are aiming to develop a new all-solid-state laser system instead of conventional erbium lasers, and recently we developed an all-solid-state, wavelength-tunable, nanosecond pulsed Cr:CdSe laser, which enables laser oscillation in the spectral range around 2.9 μm [7].
