Recently, a new high field/high frequency ESR system has been developed in KYOKUGEN Osaka University. The ESR system consists of the far infrared laser and the Gunn oscillator as a light source, and a 70 T pulse magnet. In this paper, the detail of the high field/high frequency ESR system in KYOKUGEN Osaka University will be described, and the studies on the molecular oxygen, the S=1 dimer compound and the quasi-one-dimensional Ising-like antiferromagnet CsCoCl3 will be presented as examples of the measurements using our ESR system.
