Abstract: A laser module has a housing and a laser light source. The housing is made of a material that is pervious to light and has a first end that is provided with a lens, and a second end that is provided with an opening extending into the housing to a location adjacent to the lens. The laser light source is secured in the opening at a location that is at a predetermined distance from the lens.

Abstract: A laser module has a laser driver that emits a green-light laser, and a reflector arranged in front of the laser driver, with the reflector receiving the emitted laser. The reflector partially passes the laser and partially reflects the laser. The laser module further includes an automatic control circuit coupled to the laser driver, the automatic control circuit having a light detector that receives the reflected laser, and based thereon, adjusts the output power of the laser driver.

Abstract: A light adjustment device for a laser oscillating cavity has a laser base having a housing that defines a laser chamber that retains a laser diode therein, and a fixing seat disposed at one end of the housing. The light adjustment device also includes an upper cover that is removably coupled with the fixing seat to define a spherical groove, an adjuster body having a ball and an adjusting shaft, and an oscillating cavity holder adjustably retained inside a bore that extends through the ball.

Abstract: A light adjustment device for a laser resonant socket having a laser base having a housing that defines a laser chamber that retains a laser diode therein, and a fixing seat disposed at one end of the housing. The light adjustment device further includes an upper cover that is removably coupled with the fixing seat to define a spherical groove, and an adjuster body having a ball and an adjusting shaft, with a resonant socket room defined in the ball, and with a laser resonant socket retained inside the socket room. The ball is seated inside the spherical groove in a manner such that the ball can be pivoted inside the spherical groove to adjust the orientation of the ball and the adjusting shaft with respect to the laser base.

Abstract: A method of manufacturing a laser module is provided, which includes the steps of providing a one-piece cylindrical housing having a bore, a front window and a rear opening, securing a lens piece in the bore adjacent the front window, introducing a laser diode into the bore through the rear opening, applying a force to the laser diode to insert the laser diode into the bore while simultaneously focusing the lens, and ceasing the application of force when the lens has been accurately focused.
