Passively Q-Switched Ho：SSO Laser by Use of a Cr2＋：ZnSe Saturable Absorber
A cw operation and a passively Q-switched （PQS） Ho：SSO laser （Cr2＋ ：ZnSe as a saturable absorber） end-pumped by a TIn：YAP laser operating at near room temperature are reported.

| Summary: | A cw operation and a passively Q-switched （PQS） Ho：SSO laser （Cr2＋ ：ZnSe as a saturable absorber） end-pumped by a TIn：YAP laser operating at near room temperature are reported. It is the first time to report a PQS Ho：SSO laser. For the ew mode, a maximum cw output power of 3.0 W is obtMned, corresponding to a slope efficiency of 31.4%. For the PQS mode, a Cr2＋ ：ZnSe is used as the saturable absorber, with transmission of 88.4% at 2112nm. A maximum pulse energy of 1.29mJ is obtained, corresponding to the pulse repetition frequency of 2.42kHz. In this study, we change the distance between Cr2＋ ：ZnSe and the output mirror to research the pulse characteristic of the PQ, S Ho：SSO laser. The minimum pulse width of 73.5ns is obtained, corresponding to the pulse energy of O. 9 mJ and the pulse repetition frequency of 2.65 kHz. |
