Abstract

1.57μm OPO laser is designed to meet project needs.OPO lasers are realized with Cr4+:YAG passive Q-switch for two different unstable cavities.Under the power supply of 7J,laser output at 1.57μm is attained with high beam quality.For one of the cavities,the laser output energy and divergence are 6mJ and 3.0mard respectively.For the other cavity,4mJ and(3.0mrad.)The difficulty of poor beam quality of OPO is overcome with the simple and compact structure.
- nonlinear optics,
- OPO laser,
- high beam quality,
- eyesafe laser rangefinder
