However, these two structures have disadvantages such as low power, high cost, poor heat dissipation capability and heat sink electrification.

Hence the emergence of F-mount (such as figure 1 ) packaging form (a high-power semiconductor laser and its preparation method, Chinese invention patent, CN101465516A), this patent overcomes the shortcomings of C-mount and CT-mount, and has high output power and high safety (the heat sink is not charged ), long life and strong thermal conductivity, etc., but there is no temperature and power detector to monitor the working state of the laser, and it does not have the ability to monitor the working state of the laser in real time, and cannot give an alarm signal, making the laser in an unmonitorable state
