Introduction The development of solid state 2 m Tm Ho lasers has remained a topic of particular interest for many years due to a number of possible applications such as coherent laser radar atmospheric sensing a possible pump source for an optical parametric oscillator operating in the mid-infrared region and medicine. In recent years significant progress in understanding the basic phenomena underlying Tm Ho laser operation as well as in developing high power lasers has been achieved Tyminski et al. 1989 French et al. 1992 Petrin et al. 1992 Jani et al. 1991 Jani et al. 1995 Yu et al. 1998 Alpat ev et al. 1998 Alpat ev et al. 1993 Barnes et al. 1996 Lee et al. 1996 Rustad Stenersen 1996 Bruneau 1998 Bourdet Lescroart 1999 Jackson King 1998 Sudesh Asai 2003 Sato et al. 2004 Walsh et al. 2004 Galzerano et al. 2004 Izawa et al. 2000 Yu et al. 2006 Zhang et al. 2006 Louchev et al. 2007 and 2008 and recently reviewed by Eichhorn 2008 and Walsh 2009 .
