Example Embodiment

[0016] Example 1:

[0017] When there are 4 long slots in the sheave, the combination of three groups of lenses is an example to illustrate the present invention:

[0018] like figure 1 As shown, dial 1 is placed on the left side of focusing cavity 7, sheave 2, total reflection lens mounting plate 3, total reflection lens I, II, III are placed on total reflection lens mounting plate 3, and in focusing cavity 7 A laser source 9 and a round rod 8 containing a laser working substance are included, and a light-emitting lens mounting plate 11 is placed on the right side of the light-gathering cavity, and the semi-transparent and semi-reflective lenses I, II, and III are placed on the light-emitting lens mounting plate 11; each The lenses are individually adjustable so that each set of lenses can be precisely aligned to meet the conditions for laser generation.

[0019] When the dial 1 rotates, it drives the sheave to rotate, and the locking arc is just in the disengaged state....

Example Embodiment

[0024] Example 2:

[0025] When the sheave 2 has 3 long grooves, such as figure 1 As shown, the multi-wavelength laser generating device consists of a set of groove wheel intermittent mechanism, a full-reflective lens mounting plate, a semi-transparent and semi-reflective lens mounting plate, a rigid shaft, and a concentrator containing laser working material and laser source (lamp). The optical cavity is composed of multiple sets of reflective lenses; its feature is that multiple sets of movable full-reflective lenses or semi-transparent and semi-reflective lenses are set in a fixed light-gathering cavity, and a sheave intermittent mechanism is set inside to control the movement of the lenses;

[0026] When working, the sheave mechanism can convert the constant-speed rotary motion of the dial 1 into the intermittent rotary motion of the sheave 2, which moves and stops. Place the groove wheel mechanism, the full-reflection lens mounting plate 3, the laser source 9 in the l...

[0029] Example 3:

[0030] A multi-wavelength laser generating device, including a sheave intermittent mechanism composed of a dial 1 and a sheave 2, a light collecting cavity 7 composed of a round rod 8 containing a laser working substance, and a laser source 9, two of which are respectively placed in the light collecting cavity 7 The reflecting mirrors on both sides are equipped with discs, multiple groups of total reflecting mirrors and half reflecting mirrors with different parameters, the number of reflecting mirror groups is equal to or less than the number of grooves of the sheave 2. The sheave 2 of the sheave mechanism, the full-reflection lens mounting plate 3, and the light-emitting lens mounting plate 11 are coaxial and rigidly connected. The total reflection mirror and the half reflection mirror are respectively placed on the total reflection mirror mounting plate 3 and the light-emitting lens mounting plate 11, and the center of the disc is the origin, the dista...

Abstract

The invention relates to a multi-wavelength laser generation unit which is characterized in that: an all-reflective lens installation plate, an emitting lens installation plate and a groove pulley on the shaft of a groove pulley intermittent mechanism of a resonant cavity are connected through a rigid shaft, and the all-reflective lens installation plate, the emitting lens installation plate and the groove pulley rotate synchronously; an all-reflective lens and a semi-permeable half reflector are respectively arranged on the all-reflective lens installation plate and the emitting lens installation plate, the two lenses of each group of lenses are ensured to be coaxial, the number of the lens groups is equal to or smaller than the number of radial slots, the distances of the lenses from the center of a disc are equal and the lenses are lined according to the angles of the radial slots, so that when the groove pulley rotates to each stopping position, all groups of lenses can move to the same fixed position; a condenser cavity is arranged between the all-reflective lens installation plate and the emitting lens installation plate, and a laser source and a round bar which contains a laser working substance are arranged in the condenser cavity; and the groove pulley of the groove pulley intermittent mechanism is matched with a dial. The multi-wavelength laser generation unit has the characteristics of compact and mature structure, high conversion speed, strong practicality and the like, and can obtain different laser emission frequency by changing the rotating speed of the dial; simultaneously, due to the only one fixed condenser cavity, power supply and cooling can be easily realized; and the structure is simple, the dimension is small, the manufacturing is easy, the mechanical efficiency is high, transposition can be realized stably and intermittently, the work is reliable and the like.

Description

technical field [0001] The invention relates to a multi-wavelength laser generating device, which is a device for generating multiple wavelength lasers and emitting the lasers of various wavelengths in sequence. Background technique [0002] The current solid-state laser is composed of a concentrating cavity containing a laser working substance, a laser source (lamp), and a set of reflective lenses including a total reflection mirror and a half-transparent mirror. The laser substance will be processed into a round rod. The axis of the round rod is the optical axis of the laser. The laser source (lamp) needs power supply and cooling. The half-transparent and half-mirror are on the same axis, that is, the optical axis of the laser. The three constitute a laser resonator. When the conditions are met, lasers with several wavelengths will be generated, and because of the limitation of the lens parameters, there will only be one wavelength. The energy of the laser is strong, whic...
