755nm Long-Pulse Laser Module
Categories:
CRYSTECH based on the market demand for 755nm laser hair removal and combined with the characteristics of self-produced Alexandrite crystal materials, has designed and developed the 755nm long pulse laser module. This product adopts a dual-lamp parallel pumping mode, with greater energy and longer service life; the Alexandrite crystal adopts a plano-concave resonant cavity design scheme, with a more compact structure, better stability, simple operation, and easy maintenance of the whole machine equipment.
Alexandrite crystal is a broadband tunable laser crystal with a wavelength tuning range of 700–850 nm. Its emission spectrum peaks around 755 nm, making radiation of 755 nm laser one of its key applications. The 755 nm laser is widely used in fields such as laser medical cosmetology and laser hair removal.
In response to market demand for 755 nm laser, CRYSTECH has designed and developed this 755nm long-pulse laser module. This product adopts a dual-lamp parallel pumping mode, featuring high energy output and long service life. The module offers a compact structure, enhanced stability, ease of use, and simplified maintenance for integrated devices.

Module Interfaces:
1.Electrodes:
Red wire: connect to the positive terminal of the power supply.
Black wire: connect to the negative terminal of the power supply.
The two lamps are connected in parallel.
2.Coolant Inlet/Outlet ports are with G1/4-thread. Customers can connect it using their own connectors with G1/4 thread (thread length less than 10 mm). Alternatively, the optional PC12-G02 quick-connectors (supplied in the package) can be used, which is compatible with a 12 mm outer diameter water pipe.
Precautions:
1.Wear appropriate laser protective eyewear during installation, laser tuning and operation.
2.Be aware of the laser output direction during installation.
3.NEVER operate the laser module without coolant flow. Verify that the cooling system is fully operational before powering on the laser module.
