1.Vertical-External-Cavity Surface-Emitting Lasers

Our VCSEL is an external cavity lasermodule that can directly output near infrared or visiblelasers. The module works like an external pump lasemodule and has a compact structure, small size, highoptical , and wide laser wavelength coverage.

The VCSEL laser module can be used in laser processing, Laserdemonstration, laser medicine and other applications. This module includes a laser gain chip, an optical lens, a frequency conversion lens, and many sets of lens devices.

The laser wavelength of the VCSEL module is the outputwavelength produced after generatingthe frequencydoubling effect by using nonlinear crystals.Its laserwavelength can be selected in accordance with the parameters of the different lenses and filters con- figured in the cavity.

In addition, oursingle-mode VCSEL covers the 750-900nmband, maintaining high output performance whilehaving improved energy efficiency. Through integratedpackaging, we integrate single-mode VCSEL chips withtemperature controllers and temperature sensors tosatisfy the requirements of various application.

Based on these advantages, we believe that single-modeVCSEL becomes an ideal option for atomic sensing. spectral analysis, high-accurate instrument, and otherfields.
